"The Pilbara field, Western Australia, is the principal producing cente
tantalite in Australia. Messrs. Young and Moulden, of Adelaide, work lea'
at Wodgina and also purchase any small lots raised. The production in 1"
was 19.46 tons, valued at 2,357. In 1927 the output fell to 16.28 tons,'!
the value was higher, viz, 3,808. The output is regulated by tho dem
The firm mentioned is under contract to sell tho whole, output to an Amerl
concern. Tantalite also occurs in association with tin in tho same district
at Greenbushes, but the separation is a difficult matter. It has also
reported from Coolgardie.

DOMESTIC PRODUCTION
During 1928, as in precoding years, the principal interest in ti nium was in its use in pigments. As rutile is comparatively rare, o . ilmenite has been used for this purpose, and the production of tit nium has been mostly in that form.

All three of the new operations are reported to be on nelsonite, a;
dike rock composed typically of rutile and^patite, although in some?
dikes other rock-forming minerals, such as feldspar and quartz, arqj]
also found.
/
If operations actually begin a quantity of apatite about equal in.
quantity to the ilmenite and of comparatively high purity will bqj
roduced. There is at present no known market for this phosphate,!
ut it seems probable that some use may be found for it. Apatite is|
said to be less soluble in sulphuric acid and therefore more difficult)!
to make into commercial fertilizers than the phosphates of the sediJ
Cmentary rocks; when produced in a comparatively pure crushed form!
however, it may form a profitable by-product.
J
Many bauxites carry considerable titanium dioxide, and Indian!
bauxite is reported to carry as much as 11 per cent of Ti02. At the
East St. Louis plant of the Aluminum Ore Co., a subsidiary ofj
the Aluminum Co. of America, the waste sludge daily discharged!
from the treatment of bauxite contains more than 75,000 pounds ofj
Ti02. The results of experiments (see reference in bibliography onl
page 119) carried out by W. II. Coghill, of tho U. S. Bureau of Mines,]
on deslimed sands carrying 24.33 per cent of Ti02 encourage further!
work on gravity separation of the titanium dioxide.
'g
The market for titanium minerals is very limited; sales are all ati
prices which are more or less a matter of bargaining. Ilmenite cite-f
taining 50 per cent of Ti02 was quoted by the Engineering and Minings
Journal at $9.50 to $11 per long ton. Itutile in carload lots wasfi
' quoted at 9J^ cents per pound. The best artificial titanium dioxide!
was quoted at the beginning of 1928 at 44 cents per pound in 300-]
pound barrels and on June 1 at 35 cents.

"The elements present in ordinary malleable iron are: Iron, phosphorus, marie
ganese, sulphur, silicon and oxygen. Involution phosphorus is harmless, bud iron phosphide causes brittleness and loss of strength. The manganese-sulphur]
ratio must be carefully controlled with manganeso in slight excess, but th%
absolute amounts are not so important. Low carbon with high silicon make the strongest and most ductile iVon. Titanium, nickel, uranium and zirconium
act like silicon in precipitating carbon. Inhibitors of graphitizntion are abnofj! mal amounts of sulphur or manganese and antimony, boron, cerium, chromiuiM

In 1928 tungsten minors of the United States sold an equivalent of
1,208 short tons of concentrates carrying 60 per cent of tungsten
trioxide (WO3) for $753,900, and of thoso sales, 180 tons came from
stocks. Very little stock was held at the end of 1928, and the pro
duction for the year was somewhat less than the sales in 1927, which
amounted to 1,164 tons, valued at $724,000. Tungsten ore was
produced and sold in 1928 by 12 companies. Eight of these com
panies, employing 210 men, produced 93 per cent of the total output:

Imports and exports of zinc pigments as a wholo increased in
both quantity and value. Imports were equivalent to 3 per cent
and exports 5 per cent of the domestic sales. Lithopono was the
principal import and ranked second in experts, whilo zinc oxido
was the principal export and ranked second in imports.
An outstanding feature of the lead and zinc pigment industry
during the last few years has been the severe competition between
white lead and other pigments for the paint trade. The effect of
this is roughly indicated in the comparative salos of the pigments
concerned. Sales of white lead in oil decreased from 153,000 tons
in 1922 to 112,000 tons in 1928. During the same period the com
bined sales of zinc oxide and lithopone increased from 212,000 tons
to 361,000 tons. As three-fourths of the lithopone and about one-
third of tho zinc oxide, produced in the United States are used in
the manufacture of paints, tlioso figures indicate tho marked degree
to which the zinc pigments have invadod the paint industry at the
expense of white lead.
The rapid expansion in the use of nitrocellulose paints in rocont
years has not materially altered tho quantity of pigmonts consumod.
The average nitrocellulose paint contains considerably less pigment
per gallon than oil paints, but a heavy pigment priming coat and more
finishing coats are used to offset the low pigment content. White
lead is seldom used in these paints owing to its chemical instability
in contact with nitrocellulose products.. Zinc, oxide and lithopeffe
are the pigments generally used in ni trocellulose paints at the present
time, but as a low pigment content is desirable an increased use of
high hiding-power pigments, such as titanium- oxide and zinc sulphide,
is a possibility for the future.

COMPETITION BETWEEN PIGMENTS
Throughout the nineteenth century white lead was used almost!
exclusively as the pigment base in the manufacture of paints, but!
during the last 25 years its dominant position has been challenged by*
the competition of zinc oxide and lithopone. The increasing use of!
these two pigments, particularly lithopone, is duo to their lower!
first cost and to the constantly improved properties that have been!
attained as a result of scientific research on the part of the producers,!
Production of lithopono hjis increased from less than 30,000 tons ini
1913 to more than 200,000 tons in 1928, three-fourths of which iaf
used in the manufacture of paint.
I
Another influencing factor in the pigment industry has boon thel
development of nitrocellulose paint, lacquer, and onamol9. Nitro-|
cellulose paint was dovoloped for uso in tlio automotive industry, inf
which the practico of mass production requirod a satisfactory paint!
that would dry quickly and thus assist in speoding up the production!
process. During the past few years, however, its use has extended tot
many other branches of industry; in 1927 more than 11,000,0003
gallons of nitrocellulose paint, lacquer, and enamels were produced.!
This represents between 10 and 15 per cent of the total volume of!
paint and varnish produced in the United States
40 per cent over 1926. Although it is impossible

Zinc sulphide has long been noted for its excellent pigment qualities;;!
and is one of the principal constituents of lithopone. Its use unmixed 'l ns a pigment, however, has boon very limited in the past owing to its?|

WHITE LEAD
White lead is the basic carbonate of lead an

LEAD AND ZINO PIGMENTS A
It ia estimated that more than 85 per cent of the white lead pro duced in the United States is used in the manufacture of paint. It is the only important whito pigment that is used unmixcct with other pigments in oil paints; it is also used in varying proportions in many' mixed pigments. The dry white lead is used in paints, as a constituent
of the glaze used in the finer grades of pottery, and to some extent in
the manufacture of rubber. The United States produces an export surplus''of about 0,000 tons
annually, most of which is manufactured in bond from foreign lead.
BASIC LEAD SULPHATE
Basic lead sulphate is also known as sublimed lead and is marketed
in two forms, "white" and "blue." The white variety is usually
made by vaporizing powdered galena at a high temperature in the.
presence of air, which oxidizes it to the basic sulphate. The resultant
fume is collected in bags, and owing to the zinc content of the ore,
used it usually contains about 5 per cent of zinc oxide. This product
is usually not as white as basic carbonate white lead but has a more
stable color in the presence of sulphur gases. It is used chiefly in the
manufacture of prepared paints and mixed pigments. A small
amount is used in the manufacture of rubber. Some sublimed lead
is made from pig lead.
The blue variety is generally a by-product of the smelting*bf pig
lead and is collected from the fumes leaving^the smelting furnaces.
Its color is due to small amounts of carbon and lead sulphide. Paints
made from blue load are- especially useful' as protective coatings on
metallic surfaces. Some blue lead is also used in the manufacture
of rubber.

, ' . LITHARGE
Litharge is the monoxide of lead and is produced by the oxidation of molten lead at ft moderate temperature in a reverberatory furnace. The oxide forms.on the surface of the molten metal and is raked off. into iron pots. The texture and color of the litharge, which affectT its use in the various industries, are controlled by the temperature ' of the furnace and the method of cooling. The chief use of litharge is i in the manufacture of storage-battery plates. The negative plates '
are usually made of straight litharge, whereas the positive plates i
are a mixture of red lead and litharge. It is estimated that more i
than half the litharge produced in the United States is used in the ! battery industry. The second largest use of litharge is in the rubber ;j industry where it acta as a cure accelerator and toughener in the:
production of mochanical rubber goods and rubber clothing. Other j uses are in the manufacture of load-chromate color pigment, in tho;
refining of petroleum products, in the manufacture of insecticides, i pottery glaze, and enamel ware, in making glass, and as a drier in 1 the manufacture "of varnish and linoleum.
RED LEAD
Red load is the tetroxide of lead and is made by heating powdered j litharge at a modorate temperature in a "coloring oven." The; marketed product varies in compoi'.tion, averaging about 85 per ; cent pure red lead and 15 per cent 1: harge; the latter is unchanged '
in the process of manufacture. About two duction is used in the manufacture of stora an important pigment in paints used as a pro surfaces and accounts for the familiar orange .all steel construction. Red load is the mos compounds used in the production of flint also used in potter's1 glaze, enamel ware, and facture of varnish.
ORANGE MINERAL
Orange mineral is a form of red lead; it composition but differs in physical properties gravity and lighter color.. It is usually mad under a process that requires groat care an (the price is highor than that for any of th Orange mineral is used chiefly in the man vermilion color pigment known as eosin lak - production of printer's inks and enamels.

in making automobile tiros, tubes, and accessories, which represent
about 76 per cent of the entire rubber industry.
Zinc oxide is seldom used alone as a paint pigment as it dries to
a hard smooth surface which on aging tends to crack and peel off,
leaving an unsatisfactory surface for repainting. -It, has a more]
stable color and costs less than white lead, has excellent white colon
and covering properties, and is durable. Theso many advantagek,
make zinc oxide a useful constituent of mixed paints, in which itj
finds a large usage. It is generally mixed with lithopone, white;
lead, and inert pigments.
Zinc oxide is also used in the manufacture of oilcloth and linoleum]!
pottery glazes and glass, celluloid, druggists' supplies, printer's inks,;
leather finishes, ana for many othor purposes.
The United States produces an exportable surplus of about 13,000]
tons annually.
LEADED ZINC OXIDE
f
Loaded zinc oxide is made by a method similar to the American]
process of making zinc oxide. The ore used contains lead in varying!
proportions, and the finishod product may contain from 5 to 35 per,
cent of basic lead sulphate. The properties of this pigment aro similar]
to those of zinc oxido and basic lead sulphate. It has fair hiding power;
but is not so white as American .process zinc oxide. Loadoa zinoj
oxide is used chiefly in tho manufacture of phint.
^
* LITHOPONE ...
Lithopone is the newest of the important white pigments, andl
its introduction into the`United States datos back to the close of!
the nineteenth century. It contains about 70 per cent of barium.sul-J
phate and about 30 par cent of zinc sulphide. The latter, a powerful!
pigment, is responsible for the useful pigment qualities of lithopone.!
The process of manufacture consists in mixing proper proportions ofj
solutions of barium sulphide and zinc sulphate. The resulting pra-l
cipitato is heatod to a rod heat and plunged into cold water, aftpr|
which it is ground, dried, and powdered.
'
The use of lithopone in the United ptateg has increased rapidly and!
has spread to many industries. Its chief use isdn paint manufactured
in which it is favored on account of its low cost and many good
qualities. Formerly the use of lithopone was confined to interior
paint, as the pigment would discolor in sunlight. In recent years]!
however, the refining process has been changed, and it is claimed! thatf
lithopone with a stable color suitable for exterior paints is nowj
being produced. It is generally mixed with other pigments, notably
zinc oxido.
.
f'S
A large quantity of lithopono is used in the manufacture of oilcloth!
and linoleum, artificial leather finishes, window shades, and printer's!
inks. The distribution of tho 1927 and 1923 sales of lithopone i|
given on page 352.
The United States has a small excess of lithopone imports overj
exports.

LEAD AND ZINO PIGMENTS AND S
ZINC SALTS
Zinc sulphate, sometimes known as white vitr
by treating secondary zinc material with dil
which upon evaporation yields the white crystal
to some extent in calico printing and in dyeing,
oil, as a disinfectant afid astringent, and as a siz
to painting. In addition to theso uses, severa
used yearly in the manufacture of lithopone, bu
an intermediate product it is not separately reco
;,of Mines.
'
Zinc chloride may be prepared by treating
chlorine, or with hydrochloric acid, the lattor b
used. Practically all zinc chloride produced in
is made from scrap metal or secondary materia
ashes, skimmings, and galvanizer's scrap. Owin
properties it is usually marketed in solution, alt
may be obtained in air-tight containers. Zin
.chiefly as a preservative of timber but is also u and disinfectant, in the refining of petroleum, in
in the manufacture of hard fiber, for medica
dentistry.

IMPORTS AND EXPORTS
Lead pigments.--Imports of lead pigments into the United States are relatively insignificant. In 1928 imports of white lead and red, load decreased, while imports of litharge and orange mineral increased.. Exports of whita-lead pigments increased 7 per cent in 1928 and amounted to 4 per cent of the total domestic output of basic car bonate white lead. Unitod Kingdom took 66 per cent of the whitelead pigments exported in 1928. Combined exports of red lead and litharge increased 46 per cent and amounted to 2 per cent of the total domestic production of these two pigments.

Zinc jngmcnts and salts.--Lithopone is the principal zinc pigment
imported into the United States. Imports of lithopone increased 24 per cent in 1928 and were equivalent to 5 per cent of the domestic
output. Imports of zinc oxide did not change materially in 1928;
they were equivalent to less than 1 per cent of the domestic produc
tion. Imports of zinc sulphide have increased from about 8,000
pounds in 1926 to 338,000 pounds in 1928. Imports of zinc chloride
and zinc sulphate increased substantially in 1928. The Netherlands
supplies about 75 per cent of the zinc pigments imported into the United States.
Zinc oxide is the principal zinc pigment exported from the United
States: in 1928 there was a slight increase in the quantity shipped
abroad. Exports amounted to 9 per cent of the domestic output.
Canada took 43 per cent of the total, and United Kingdom took 29
per cent. Exports of lithopono increased 58 per cent; imports, how
ever, exceeded exports by 6,600 tons, or the equivalent of 3 per cent
of the United States output.

ZINC PIGMENTS AND SALTS
Zinc oxide,: leaded zinc oxide, and lithopone are the principal), pigments of zinc, and the chloride and sulphate are the principal^
salts. These products are manufactured from various zinciferous materials, such as ores, metal, and secondary substances. In 1928
the total zinc content.of all zinc pigments and salts produced and soldi
amounted to 187,031 tons, an increase of 4 per cent over 1927. This.

Since 1910, the first year for which satisfactory data

postwar period. Since the production of primary zinc
at about the same rate, however, there has been little

monthly output as in July, after which there was a definite upward
trend. Outstanding features in the production of refined primary
lead in 1928 were the 6 per cent docrease from domestic ores and the
21 per cent increase from foreign materials. The latter was the net
result of the 34 per cent increase in the refined lead produced from
foreign base bullion and the 18 percent decrease in the amount obtained
from smelting foreign ore.
\
The downward trend in the price of lead, so apparent in 1927, con-?
tinued during the first part of 1928, reaching the low point of tho year,
early in March; during the remainder of the year the trend was defi
nitely upward. The New York monthly average was 6.50 conts for
January. The low average for the year was 6 02 cents for March. By,
October the average was again 6.50 cents. There was a slight reces
sion in November, but the price again averaged 6.50 cents for
December. The average for the year was 6.31 cents in 1928, as'
compared to 6.75 cents in 1927. Owing to the depressed London
market in 1928 the New York price exceeded the St. Louis average
by only 0.17 cent per pound, as compared to 0.23 cent in 1927. Tne,,
New York price was 1.73 cents above the London average in 1928, as f
compared to 1.50 cents in 1927.
)
The recovery'of secondary lead in pig lead and in alloys in 1928?
broke-all . previous records; it amounted to 308,600 tons or the .;
equivalent of 49 per cent of the primary lead produced from domestic j
ores. Secondary lead recovered as pig lead amounted to 138,000r'
tons or 45 per cent of the total secondary lead recovered in 1928.
The total consumption of lead in the United States, as estimated t
by the American Bureau of Metal Statistics, amounted to 930,500 ',
tons hi 1928, an increase of 11 per cent over 1927 and surpassing all)?
previous records. Storage batteries ranked first among the consum-'j
era of lqad in 1928 and showed a 26 per cent increase over 1927 in
the quantity of lead used. Cable covering Was next in importance
and used 12 per cent more load in 1928 than in 1927. White lead*,
was the third largest consumer in 1928, but showed a slight decrease
in the quantity of lead used. This industry, which consumed 23 per
cent of the total lead used in 1922, took only 13 per cent of the total
in 1928. Owing to the large increase in the recovery of secondary'
lead there was a decrease of 1 per cent in the apparent consumption
of primary lead.
-
Mine production of lead in the United States showed a 6 per cent
decrease in 1928, fairly general throughout the States--production
in the Western States having been curtailed 6 per cent and that in . -
the Mississippi Valley States, 5 per cent. Oklahoma suffered the
largest tonnage cut, and Virginia was the only State in which there
w r b a substantial increase.
,
General imports of lead in base bullion increased about 10,000 tons ,?
or 9 per cent, largely as a result of importations from Peru, where:-;
an American copper company began lead-sinelting operations. Im
ports of lead in ore decreased nearly 15,000 tons, or 36 per cent, i-;
largely as a result of smaller shipments from Mexico. Exports of.1)
refined pig lead .from domestic ores were nearly 12,000 tons (461 per t
cent) greater in' 1928 than in 1927; at the same time exports of '
foreign pig lead decreased nearly 21,000 tons, or 17 per cent.
An important development in the United States lead industry in
1928 was the organization, on November 14, of the Lead Industries
T.yun
: Association, comprising both producers and con
fpurposes are to promote service among lead in
munity at large, disseminate accurate informati
of leaa products, collect statistics on marketing
-lead and its products, and develop methods to;im

engaged in mining, smelting, and manufacturin
States, Mexico, Canada, and South America. E

A' ustra"lia was th'i'rd', with 9- per cenntt of tne wor

it increased its output 2 per cent. Spain fell off
fifth, with slightly less tnan 8 per cent of the wo
and Belgium followed in order, with little change i
increased its output 19 per cent, and Peru and P
.their production considerably.
,
The London price of lead m 1928 averaged 2
or 4.58 cents per pound, a decrease from 1927 o
pared with a decrease of 7 per cent in the Ne
low price prevailing in Europe caused European p
curtailment of output along the lines of the Zinc

negative. Arrangements were made for collect
tistical data, but it was concluded that world

would be held in March, 1929. .

r * PRIMARY LEAD
l REFINERY PRODUCTION
; lead is classified by the Bureau of Mines as primary or secondt ary, according to whether it is derived directly from the smelting of
i ores anP frm base bullion or is reclaimed from industrial lead scrap/:
borne plants.that ordinarily smelt ore frequently add lead scrap to the
, charge so that the resulting product is an inseparable mixture of lead
from both sources and is all marketed as refined pig lead. Never-
roeless, the smelter calculates the quantity of secondary lead so pro
duced, thus enabling the Bureau of Mines to obtain a consecutive rec
ord of the amount of primary lead being supplied to the trade each
. yoar.
.
Primary lead may be produced from domestic ore or foreign ore and from base bullion. The smelting of lead-bearing ores from the Western
States yields an impure pig lead (base bullion) that contains valuable
mounts of silver and gold, m addition to objectionable impurities such as copper, arsenic, and antimony. This base bullion is given lurthor treatment for the removal of the impurities and finally emerges
rofined pig lead The smelting of lead-bearing ores from the Mississippi Valley and Southern States yields soft lead pure . enough for marketing, but some of it is desilverized and is designated , P^this report as desilverized soft lead. Foreign ore is first smelted . into base bullion and then rofined for market. Foreign base bullion
I lnt0 kbe United States is also refined before marketing l- of these products for market are referred to as refined lead. The f,- -following table gives a summary of the rofined primary lead produced s in the United States from 1720 to 1928.

.
The following table shows the source of the ore and foreign bas bullion from which refined lead was produced in the Unitea State from 1919 to 1928. Most of the base bullion produced in the West' ern States is shipped to the Mississippi Valley and Eastern States fo refining. In reporting the production of lead by sources most of th refiners make the distribution on the basis of base bullion, so tha
the total lead given in this table as from domestic ore include both base bullion and refined lead and thus contains a large pa
of the antimomal lead produced from domestic ores. The tot`! here given for 1928 exceeds the total production of refined lead fron domestic ores, as shown on page 611, by 16,496 tons. The productio

SOFT LEAD
,, A large part (44 per cent in 1928) of the lead produced in the Uni
States froin domestic ores is derived from the nonargentiferous&
ores of the Mississippi River Basin. The two principal ore-prodif
areas are the Southeastern Missouri district and the tri-State dial (Joplin) at the junction of Missouri, Kansas, and Oklahoma.. $
former district produced about 71 percent and the latter 26 per'
of the total soft lead in ore mined in 1928.
.
. Eighty-two per cent of the soft pig lead produced in 1928:
marketed without desilverizing, and 18 per cent was desilveriz
The former, which is known in the trade as chemical lead, conta:
1 to 4 ounces of silver to the ton and 0.04 to 0.08 per cent copper)
is 'Used chiefly in the manufacture of cable, pipe, and sheets. De
venzed' soft lead is used largely in the manufacture of white le'L
where a .very pure product is required. X.A' substantial quantity of high-grade lead concentrates fromi.t Mississippi Valley is used each year in the manufacture of lead p'
ments, principally ; basic lead sulphate (white sublimed lead) ,a
leaded zinc oxide. In 1928 more than 10,000 tons of soft lead w recovered in this manner.

. ANTIMONIAL LEAD
Antimonial lead is an important by-product of the refining of base'
bullion. In 1928, 33,058 tons of primary antimonial lead was prow
duced, which contained 29,626 tons of lead, an increase of 36 per cent
over the 1927 output of antimonial lead and equivalent to 6.5 per cent^
of the total refined,lead produced from base bullion. The principal
uses of antimonial lead are in the manufacture of storage batteries
bearing metal, and type metal. The consumption of antimonial lead'
m storage batteries increased nearly 40 per cent in 1928. The fol
lowing table shows the production of primary antimonial lead from
1919 to 1928. '

derived from the sources shown in the following table. Refined pig
lead is used in the manufacture of white lead, litharge, red lead. sut
limed lead, and orange mineral, and in 1928 about 243,000 tons of the"
lead contained m lead pigments was derived from refined pie lead:
white lead accounted for 52 per cent of it, litharge 32 per cent, red

WORLD ASPECTS
WORLD SMELTER PRODUCTION
The following table shows the world smelter production of lead:
from 1924 to 1928, so far as statistics are available. Official figures
are used wherever possible. For countries for which official data are not yet available the figures are taken from the yearbook of the
American Bureau of Metal Statistics and other reliable sources
but in later reports the official statistics will be substituted as
received.
"
There is always a possibility of duplication in figures showing world production, for some countries send "work lead" or base bul lion to other countries for refining. Furthermore, secondary and
antimonial lead are often included in the figures showing the foreign,
production, so that to put the United States on an equal footing in> the statistics it would bo necessary to include in its production the
domestic output of secondary lead and antimonial lead. The figures for the United States represent refined lead that was smelted in this country, whatever the source of the ore.

YUGOSLAVIA
Production of lead in Yugoslavia in 1928 was nearly 14,000 met:: tons, or 30 percent more than that in 1927. Exports were 8,800 tons' of which Austria and Hungary took 96 per cent. The Central Europea Mines (Ltd.) was the principal producer, its smelter at Mezica na'j ing produced 9,734 tons of virgin soft lead.
Trepca Mines (Ltd.), a subsidiary of Selection Trust (Ltd.), wa _ reported as developing the Stantrg lead-zinc-silver deposit near th| town of Kosovska Mitrovica. The ore body is a replacement in lim, stone. Reserves were estimated at 1,750,000 tons, averaging 11* per cent lead, 10.6 per cent zinc, and 3 ounces of silver per ton.11
IMPORTS
. The United States imports much lead in various forms, principal!
in base bullion and ore. Some of it is entered for .immediate com
sumption; most of it, however, is entered for warehouse, is smelted
and refined in bond, and is then reexported as refined pig lead or i~
manufactured products.

GENERAL IMPORTS
*
The following table shows the general imports of lead into the
United States, by classes, including both imports for immediate con,sumption and imports for warehouse. Of the total lead imported in 1928, as shown in the table, 82.9 per cent was in base bullion, 16:7 per cent in ore, and 0.4 per cent in pigs, bars, sheets, and old. Im(r
ports in base bullion increased 9 per cent in 1928, while imports i ore decreased 36 per cent.

* Revised figures.
The foregoing table is intended to include only primary lead or lea
smelted directly from ore. There are, however, some small discrep ancies which should be pointed out. Many primary lead smelter"
produce from secondary materials some lead which is insepatabl from the primary lead in the final product. Exports of lead as reporte
"above may therefore contain some secondary lead. There are ais
some inaccuracies in the statistics of imports, exports, and warehous transactions. Nevertheless, on the basis of the data available, th table gives approximately the quantity of new refined lead enterin ` into American industry each year.
The apparent consumption of refined primary lead in 1928 amounte to 657,565 tons, a decrease of 1 per cent from 1927. As the use d lead is intimately associated with the uses of other common metal^ and as the apparent consumption of primary copper, zinc, and iref increased 13, 12, and 4 per cent, respectively, it is concluded that th decrease in the consumption of primary lead was due largely^
increased use of secondary lead, recovery of which increased 12 p
cent in 1928 and was equivalent to 47 per cent of the primary lea
consumed.

MINERAL RESOURCES, 102 8----PART I
For several years storage batteries have been the largest consumer!
of lead, having taken first place from white lead in 1923. Storage batteries are used chiefly in motor vehicles, and the 26 por cent
increase in the quantity of lead used in storage batteries in 1928 is in
part a reflection of the 28 per cent increase in the number of auto mobiles and trucks manufactured in that year. Exports of storage
batteries have grown steadily from a total of about 207,000 in 1926 to'
338,000 in 1928, an increase of 63 per cent. The expansion of the :
automobile industry and export trade has more than offset the' decreased use of storage batteries in radios which resulted from the
introduction of "socket power" sets. In 1928 the use of lead in stort
ige batteries exceeded all previous years. The American Bureau of,
Metal Statistics has estimated that about 16,000,000 storage batteries-
were manufactured in 1928. The second largest use of lead is as a protective coating for copper;
vire cables used chiefly in telephone and underground transmission'
ines. The quantity of lead so used was 12 per cent greater in 1928
ban in 1927 but was slightly less than in 1926. This use appears to be sure to increase. General expansion of the use of electrical power,
uch as the large electrification programs announced by some of the
ailway companies and the development of the Boulder Dam and
dher great power projects, will require large amounts of lead-covered
able. Increasing civic consciousness will undoubtedly result in placing
many of the present unsightly overhead transmission lines under
round, as has been the custom in Washington, D. C., for many years,
iesearch work nowin progress to determine the causes and remedies
f certain defects in lead-covered cable that have limited its use in
ime industries should yield profitable results in expanding the market
>r lead-covered cable.
"
The manufacture of white lead is the third largest use of lead, but
ue that-appears to be on the decline. Prior to 1923 this industry as the largest consumer of lead and in 1922 took 156,000 tons of
ad, or 23 per cent of the total estimated lead consumption. In 1928 ;ily 123,000 tons (13 per cent of the total) was so used. The declin-
g use of white lead is duo to the substitution in paints of the cheaper igments, principally lithopone and zinc oxide, and to the increased
;o of nitrocellulose paints in which white lead is seldom used on
count of its chemical instability in contact with nitrocellulose
loducts.
During the war lead-tin-cadmium solders containing more lead and
-ss tin than ordinary lead-tin solders were developed and proved
'onomical under the high prices of tin then prevailing. Research
as since been continued and several new substitutes have been devel-
i>ed, but owing to the recent increase in the price of cadmium and
icrease in the price of tin the advantage of the lead-tin-cadmium
dders from a cost standpoint has practically disappeared.
An interesting and comparatively now use of lead is in tho inanufac-
ire of tetra-etnyl-lead for use in antiknock gasoline. Tho company aking this product estimates that tho consumption of this type of
isoline in 1929 will be 1,145,000,000 gallons and that 2,700 tons of
LEAD
| metallic lead will be used. As this quantity represe f'cent of tho total gasoline consumed annually in tho Unit ^appears to be room for a substantial increase in tho
? Nw7uses of lead developed in 1928 have been s Metal Industry as follows:1

The two major markets for lead in the United States

usually prevailing on the London market, so that the seldom exceeds tho St. Louis price by as much as the fre 0.35 cent a pghnd. The following tables show the a
