Prepared by staff of BUREAU OF MIN N49792 652 MINERALS YEARBOOK, 1967 indicates a $26.9 million drop in com parison with that of 1966. . The expansion program increasing ca pacity at the Herculaneum, Mo., smelter of St. Joseph Lead Co. to over 200,000 tons of refined lead annually, was com pleted early in 1967 after a conversion shutdown period begun in December 1966. Herculaneum production from com pany concentrates in 1967 totaled 120,207 tons of'lead metal in comparison with 90,729 tons in 1966. Output curtailed by equipment adjustments approached capac ity during the closing months of the year Operations at the I ooelc, Utah, smeller of International Smelting & Re fining Co. were suspended on May lfi in the wake of an explosion in the air blower system, without employee injury, which necessitated extensive repairs prior to resumption of operations in late June. The 50th anniversary of the blowing in of the Bunker Hill lead smeller was observed in July. In the period, starting July 5, 1917, the plant has produced over 3.3 million tons of lead and 368 million ounces of silver. The modernization and expansion program continued at the smelter with installation of a downdraft Secondary lead in 1967 represented 59 percent of the domestic production of lead from all materials and 43 percent of total supply including metal imports for con sumption. This compares with 56 per cent and 44 percent, respectively, in 1966. Raw Material Source.-- The - domestic component of smelter feed reversed the upward trend of recent years and rep resented 68 percent of the 389,000 tons of primary metal in comparison with 72 percent of the 451,900 tons in 1966./ Im ported ores and bullion supplied 125,000 t/ins of metal. The smelling of scrap at primary plants continued to decrease from the high of 1965 and in 1967 contributed only 10,300 tons, principally as antimonial lead. Raw materials and material in process at primary plants at the beginning of the year totaled 136,200 tons, lead content, of which 9-1,900 tons was primary and sec ondary materials for smelting and 41,300 tons was -in the process of smelting and re fining. Stocks of materials were gradually built up to a high of 164,900 tons at the end of October and then drawn down to end the year at 150,300 tons, of which 105,000 tons was available for smelting and 45,300 tons was in the process of sintering machine and exhaust gas system underway to eliminate air pollution and increase sulfuric acid plant output. Secondary lead output decreased about 19,100 tons to 553,800 tons from the high level of 1966. Primary plants reported an output of only 10,300 tons of secondarylead in comparison with 19,800 tons in 1966. The major demand continued in antimonial lead with a record output of 288,700 tons, 52 percent of the total secondary. The major decline was in other lead alloys, which decreased from 23 per cent of the total in 1966 to 21 percent. Soft lead output continued at about the same level undoubtedly reflecting some demand resulting from the decreased domestic primary output of refined lead. smelting Consumption of scrap materials'during the year was 726,300 tons, gross weight, in comparison with 741,OOf) tons in 1966 and 748,300 tons in 1965. Receipts of scrap at consuming plants were essentially in balance with consumption, with stocks ranging from 52,800 tons at the beginning of the year to lows of 47,200 tons in March and September, and ending the year at 58,000 tons. Battery plates supplied 73 percent of the old scrap consumed in comparison w-ith 70 percent in 1966, and drosses and residues from manufacturing and foundry sources accounted for all of the new scrap processed amounting to 101,100 tons in comparison with 112,000 tons in 1966. CONSUMPTION AND USES Consumption of lead declined in 1967 after five successive years of growth cul minating in the record high of 1.32 million tons in 1966. Total consumption of 1.26 million tons in 1967 represented a decrease of 63.JOO tons or 4.8 percent. Industry requirements again exceeded 100,000 tons monthly except for February and the vacation month of July- Consumption in each month except January and April, however, was well below- that of the cor responding month in 1966. The daily aver age was 3,453 tons in comparison with the 3,627-ton average in 1966. The decrease in consumption w-as distributed over all types of lead--soft lead, antimonial lead, and lead alloys--and over all product categories except chemicals. The two LEAD major uses of lead -- batteries and gasoline antiknock compounds--held up well, how ever, with battery requirements down only 5,800 tons (I percent) and antiknock compounds slightly increased. These two major end products required almost 57 percent of the total lead consumed and ammunition moved into third place in 1967 supplanting red lead and litharge. The requirements for ammunition have increased 29,000 tons since 1963, in fluenced by increased military needs as well as the use of sporting ammunition. I he relatively unchanged requirements for collapsible tubes, foil, plumbing, white lead, and pigments was noteworthy. A significantly lower consumption in calking lead accelerated the downward trend in this use area and solder requirements, after a slight gain in 1966, were much lower in 1967. The use of lead in red lead arid litharge, after an abnormally high level in 1966, decreased to approxi mately the level existing in 1964-65 and requirements for type metal and lerne metal continued to decline. The manufacture of storage batteries, the largest use of lead, consumed 245,200 toils of soft lead and 221,500 tons of lead in antimonial lead in comparison with 237.400 tons of soft lead and 234,600 tons of antimonial lead in 1966. Batteries are of two categories--starting-lighting-igni tion (S.L.I.) batteries used in conjunc tion with internal combustion engines and the industrial batteries used for power, lighting, and communications. Industrial batteries over the past 8 years have re quired from 10 to 12 percent of the total lead used in batteries. Shipments of S.L.I. batteries both for original equipment and replacement, totaled 41.5 million units in 1967 in comparison with 43 million units in 1966. Shipments of replacement batter ies, only slightly below the 1966 total, rep resented 77 percent of the total; original equipment batteries, down to 9.3 million from 10.7 million units in 1966, rep resented 22 percent; and export of 204.400 batteries accounted for the re maining I percent. Technological advances in battery manufacture and in improved charging equipment has materially reduced the weight of lead per battery unit to the present average of 18.8 pounds and has increased battery life from an average of 20 months in 1950 to 27 months in 1966. Greater emphasis on methods of combat ing air pollution has served to point up the depend cost, a lions o powere The posted 168,90 tons in in 196 conten declini compo Canad of plan the de supplie extent gasolin to wh toward air pol Hist metal, paints, not ap in fact by oth phasis cation rently attenua sion-re chemic Lead in gage proofin efficien slrated ings to been w quality involve ized so field o ing in cludes pesticid The in 196 black the va to 31 331,30 growth Black percen 654 MINERALS YEARBOOK, 1967 with 58 percent in 1966. Litharge, the other large item, consumed 28 percent in comparison with 80 percent in 1966. Distribution of shipments of pigments and oxides reflected the dimishing require ments for white lead and red lead in the paint industry. The ceramic requirements for white lead, red lead, and litharge also decreased as did the use rtf litharge in oil refining, nihher processing, and varnish manufacture. Manufacturers' shipments not specificially defined as to end product rep resent a major tonnage of while lead, red lead, and litharge and a substantial decline was posted for the "Other" categories for each of these materials in comparison to the high requirements of 1966. Prices.--The quoted price of lead pig ments and oxides was unchanged during the year reflecting the stable price of lead. Basic carbonate white lead was quoted at 20.5 cents per pound in carload lots, freight allowed. Red lead, 95 percent PhsOi, in carload lots, at works, was quoted at 16.75 cents per pound efleclivc in mid-October 1966. lhe price of litharge was 16.25 cents per pound for commercial grade, powdered, in carload lots, at works, also effective in mid-October 1966. . Shipments of dry white lead declined in average value per ton from $412 to $407 while the average value of white lead in oil increased from $658 to $677 per ton. 1 he total valuation of white lead shipments decreased about $) .3 million. Red lead shipments declined in average value from $361 to $342 per ton and litharge from $341 to $321 per Inn and total value de creased $5.4 million. The total value of shipments of white lead, red lead, and litharge was $46.8 million, a decrease of 16 percent in comparison with the $56 million value in 1966. Foreign .Trade.--The export of lead oxides, pigment grade, including com pounds of lead arsenate and others, de creased from 2,600 tons valued at $1.04 million in 1966 to 1,909 Ions valued at $772,300 in 1967. Canada was the lead ing importer at 666 tons followed by the United Kingdom, 175 tons and South Vict-Nam, 113 tons. Twelve other countries received shipments ranging from 1.4 to 84 tons and small shipments aggre gating 213 tons were consigned to various other countries. Imports for consumption of lead pig ments and compounds was slightly higher in tonnage hut declined in value some $784,000. White lead was received, in order of importance, from West Germany, Canada, Netherlands, the United King dom, and Japan. Red lead was chiefly supplied by Mexico (45 percent), France f 26 percent), and West Germany (25 percent), with Denmarlj, the United King dom. and Belgium-Luxembourg the other suppliers. Litharge, representing 80 per cent of the lead pigments and compounds imports, was predominantly from Mexico, 98 percent, with France, West Germany, Belgium-Luxembourg, Netherlands, and Canada the other sources. Other pigments, including leaded zinc oxide, blue lead, orange mineral, and unspecified, aggre gated 74 tons and came predominantly from West Cennany and the United Kingdom. Lead nitrate imports of 220 tons from the United Kingdom arid Republic of South Africa and 130 tons of unspecified lead compounds, mainly from Canada, made up the 3.60 tons of other lead compounds. STOCKS The stock position of all segments of the lead industry improved in 1967 although still well below normal levels. Primary producer stocks of refined lead at the beginning of the year amounted to 16,208 tons and antimonial lead stocks were 6,400 tons. The combined stocks gradually increased through May to 3.1,700 tons, declined to close the year at 18,200 tons of refined lead and 5,200 tons rtf lead in antimonial lead. I he combined stocks of metal at primary plants has thus ranged from 25,200 tons in 1965 to 22,600 tons in 1966 and 23,400 tons in 1967. The total lead in primary materials, including ore, bullion, in process, in transit, and re fined, as reported hy the American Bureau of Metal Statistics at yearend 1967 was 189,900 tons in comparison with 177,100 tons at yearend 1966 and the low of 140,800 tons at yearend 1965. Consumer and secondary stocks of lead in all forms opened the year at 90,30(1 tons and increased moderately to a peak of 114,200 tons in July and then declined to 105,800 tons at yearend. The major LEAD increase was in soft lead which comprised 57 percent of total stocks. Government inventory tons to a PRICES The domestic quoted price for common lead at New York, after two decreases of 1 cent per pound in 1966 from the De cember 1964 peak of 16 cents per pound, was unchanged at 14 cents per pound throughout the year. The foreign market, as illustrated by the London Metal Ex change, was relatively stable with daily fluctuations within a narrow range. The average monthly price in U.S. currency equivalent ranged from a low of slightly under 10 cents per pound in January to a high of ffeerreennttiaiall o tween the well abov additiona New York a favorab The Go was at t equivalen the variou tion storag FOREIGN TRADE The foreign market for domestic raw materials and refined metal continued unfavorable daring 1967. The 1,000-ton increase in refined exports resulted mainly from larger metal shipments to Japan and, also, increased small-lot shipments to other countries. Scrap shipments abroad con tinued to decline indicating the upward trend in lead raw material availability at the European smelters. General imports of ore and bullion during the first 6 months of 1967 were 15,800 tons or 23 percent above the re ceipts during the like period in 1966. The strike closure of domestic smelters relying on foreign ores during the last half of the year resulted in a 15-percent decrease for the year. General imports of metal, how ever, posted a 38-percent increase for the first 6 months and 27 percent for the year in comparison with the like periods in 1966. A large tonnage of lead in ore was moved from bond into commercial channels in 1967 and imports for consumption ex ceeded general imports by over 20,000 tons. Metal deliveries were entered for duty payment as landed and general im ports and imports for consumption were identical in 1967.

Such slags were treated to extract zinc and remaining lead by the following companies in 1967: Company American Smelting and Refining Company........................... l}o............................................................................................ The Anaconda Company............................................................... The Bunker Will Co........................................................................ International Smelting & Refining Co...................................... Plant location Selby, Calif. El Paso, lex. East Helena, Mont. Kellogg, Idaho Tooele, Utah These five plants treated 494,900 tons of hot and 34,900 tons of cold lead slag plus 4,400 tons of crude ore, all of which yielded 96,900 tons of oxide fume contain ing 62,200 tons of recoverable zinc. Cor responding figures for 1966 were 818,900 tons of feed materials, 133,600 tons of fume, and 87,100 tons Sf recoverable zinc. Secondary Zinc Smelters.--Zinc-base scrap (principally skimmings and drosses, die-cast alloys, old zinc, engravers' plates, new clippings, and chemical residues) was smelted chiefly at secondary smelters, al though about one-third was reduced at primary smelters and most sal ammoniac skimming* were processed at chemical plants. Details of the zinc recovered in proces sing copper-base scrap arc contained in the secondary copper and brass section of the Copper chapter of this volume. BYPRODUCT SULFURIC ACID Sulfur dioxide gases produced in roast ing zinc sulfide concentrate at primary zinc plants were processed to yield 900, 170 tons of sulfuric acid. At several plants, elemental sulfur was burned to produce additional quantities of acid. ZINC DUST Zinc dust data included in the tables are restricted to commercial grades that comply with close specifications as to percentage of unoxtdized metal, evenness of grading, and fineness of particles; they do not include blue powder. Zinc content of the dust pro duced ranged from 95.00 to 99.60 percent, averaging 98.46 percent. Production of zinc dust was 50,300 tons, a 9-percent reduction from the 1966 record high and a reversal of the upward trend of the pre ceding 4 years. CONSUMPTION AND USES Consumption of slab zinc was 1.24 mil lion tons, 12 percent below ihc 1966 record high and a reversal of the upward trend for the preceding 6 years. The re duced consumption was principally in the three largest industrial categories--zinc alloy, galvanizing, and brass--which con sumed 535,100 tons, 458,600 tons, and 131,500 tons, respectively. Of the 1.24 million tons of slab zinc used, 52 percent was Special High Grade, 29 percent Prime Western, and the re maining 19 percent all other grades. Galvanizing used mostly Prime Western grade while brass and bronze products con sumed mostly the higher grades of zinc. Of the 535,100 tons of slab zinc used in zinc-base alloys, 99 percent was Special High Grade. Rolling mills used 45,400 tons of slab zinc and remelted and rerolled 18,700 tons of metallic scrap produced in fabricat ing plants operated in connection with the rolling mills. In addition, a small quantity of purchased scrap (new clippings and old zinc) was melted and rolled. Small quantities of alloying metals were added for some uses. The rolled-zinc industry, however, classified these alloys as rolled zinc. Net output of salable rolled zinc de creased 14 percent to 44,200 tons, ap proximately equal to 1965 production. Stocks of rolled zinc at the mills were 1,600 tons at yearend. Besides shipments of 20,000 tons of rolled zinc, the rolling mills consumed 42,700 tons of rolled zinc in manufacturing 25,300 tons of semifabricated and finished products. Rolled zinc was produced in the form of sheet, strip, ribbon, plate, rod, and wire. Its major domestic use was for dry cell battery cases and similar cases for radio condensers and tube shields. Photoen- ZINC graving plates, weather stripping, roof flashing, and household electric, fuses were other uses. CONSUMPTION OF SLAB ZINC BY GEOGRAPHIC AREAS Ohio, Pennsylvania, Indiana, and Illinois accounted for 56 percent of the slab zinc used in galvanizing. The iron and steel industry used zinc to galvanize steel sheets, wire, tube, pipe, cable, chain, bolts, rail way-signal equipment, building and pole line hardware, and other items. Connecticut again ranked first in con suming slab zinc in brass making, followed by Illinois and Michigan. Michigan led in the consumption of slab zinc in making zinc-base alloys. Other large consuming States were Illinois, Ohio, New York, and Indiana. ZINC PIGMENTS AND COMPOUNDS Production.--Output of zinc pigments and compounds, excluding lithopone, was 296,600 tons, a 9-percent decrease from the high level of 1966 which had included record outputs of lead-free zinc oxide and zinc sulfate.
