Frederick Lalst, General Metallurgical Manager, Anaconda Copper Mining Company, Room 1720 - 23 Broadway, New York, N. T. Dear Mr. Lalst:- The East Chicago Chanber of Cosmerce will publish on December 10th, their Annual Review Number. Thl particular lsaue will be devoted to the transportation facilities and advantages at East Chicago to Its Industries. Hiay have requested each Industry to prepare a brief article outlining their uss of tha local transportation facilities In connection with the operations at East Chicago. The attached write-up has been prepared along this 11ns and Is submitted for your approval. t understand that Mr. Thayer may not be In New York during the week ending November 22nd. The Chamber of Commerce desires to have approval of tha final write-up not later than November 19th. CZj/a CC: Mr.B.B.Thayer Eiel. C. Z. Johnson, Superintendent. 1SROOI 167 N 3600 Til* operations of the International Load Refining Company and the Anaconda lead Products Company at Beet Chicago rapraaant tha final bringing Into marketable form and the distribution of materials that have originated at far distant places. So materials of local origin enter Into the product or take any essential pvt In the operation, other than fuel and a amount of fluxing material. Comparatively little of the final product is consumed In local Industries. Good fuel, labor and suitable fluxes are obtainable on satisfactory terms In Seat Chicago, howsvsr, numerous other localities could offer equal advantages In fulfilling these requirement*; - It Is principally as a center of transportation and distribution to all parts of the United States that Seat Chicago la veil adapted for the location of this Industry. ths Anaconda Copper Mining Company's production of lead Is derived from tha treatment of the complex lead-copper-zinc ores of the Western United States. the majority of these ores contain the three metals mentioned In the form of sulphides, and In addition recoverable amounts of gold and sliver. The ores are first concentrated by flotation, producing three or more products, one of vhich Is a lead concentrate, containing the greater part of the lead and silver from the ore, vlth small amounts of the other metals as Impurities. The complete separation of sine and lead by concentration is difficult and a certain amount of the lead from the ore la contained In the zinc coooenfcrate. 9M lead eoaeentrate la amelted at tha plant at the International Suiting Company at Tooele, Utah, an Anaconda subsidiary, the lead and silver are reeovered In the fom of a 'bullion* containing approximately lead, 00 02a. silver per ton and aaall percentages of antimony and other impurities. - this bullion Is shipped to the International lead Refining Company at Bast Chicago for refining. 891100MS1 N 3600.01 Sheet #2 Tha tine concentrate la treated et the Anaconda plants at inaeosda and Great Mli, Montana, for the production of electrolytic zinc. Tha lead remains In the realdue after the extraction of the zinc. This residue le melted at the Saet Helena plant of the American aaeltlng and Refining Company and the resulting bullion, similar to Tooele Bullion In analysis, le shipped to ftat Chicago for refining. Rie fiist Chicago refinery Is also to some extant a custom refinery for lead bullion purchaaed from other sources. Lead residues and drosses from all plants of the Anaconda oaapany are treated, and limited quantities of scrap battery plates, lead drosses, and secondary materials are purchased. The plant Is a Parkea process lead refinery of 96,000 tons' mnmi capacity, producing comaon desilverized pig lead, antlmonlal lead, and dors' bullion. Three railway lines enter the plant - the Indiana Harbor Belt Railroad, ths Baltimore & Ohio Chicago Terminal Railroad and the Pennsylvania Railroad. The lead bullion produced at Tooele, Utah Is molded into rectangular blocks weighing 4 tens each, loaded Into open gondola ears and shipped by rail to Hast Chicago. At the Refinery the blocks are unloaded with tongs by an overhead crane, as shown In Tlgurw 2, and are melted down In kettles holding 135 tone of molten metal. ThO antimony Is separated from the lead end silver and le concentrated and placed In marketable form aa an alloy with lead, known as Antlmonlal or "Bard" Lead. This la east Into 75 pound pigs and loaded into box care for shipment. Sheet #5 The addition of antimony hardens and Increases tie physical strength of lead, and gives It the property of producing castings of beautiful sharpness and fidelity. Antimonlal lead le used In the manufacture of storage batteries, bearing metals, type metal, ornamental novelties and a great variety of other applications. The silver and gold are removed from the lead and, in the form of an alloy of the two metals known as dors' bullion, are shipped by express to the Rarl tan Copper Works at Perth Amboy, Nee Jersey, an Anaconda subsidiary. Here they are separated electroly-tlcally sad placed In marketable form. The lead, freed of Impurities, is east Into 96 pound pigs, loaded Into box cars and shipped. Figure 3. The applications of lead are extremely varied and include lndustrlea In all parts of the United State*; notwithstanding this fact the plaata producing refined lead are comparatively few in number and transportation facilities for raw material and finished products are essential factors in their operatlan. One of the most Important applications of lead le In the production of White lead for use In paint. Hex* again ths elements entering Into the product have little to do In determining the beat location for Its manufacture. White lead la a baale carbonate of lead, containing laad, water and earbcm dloxlda; no matsrlals In any way peculiar to the Caltnet Region enter Into Its production, however the product la distributed to paint manufacturers In all parts of ths United States, and In tha facilities that It affords for such distribution Fast Chicago is predominantly fitted for ihe location of this Indnstry. rOs o o CO Sheet #4 Anaconda White Lead Is an exceptionally pure white lead produced by a unique Elec trochecd cal process developed by the Anaconda lead Products Ccep any at their East Chicago Plant. The process Is the Invention of the late Elmer A. Sperry, Internationally famous as an Inventor and particularly known to Chicago as the designer and donor of the Llndberg Beacon. Refined lssd for the white lead process is east In rectangular anode plates at the Refinery and Is delivered to the White Lead Plant by a small industrial railway Joining the two plants. The anodes are placed In electrolytic cells where the lead Is dissolved and converted into white lead. Though the anodes are of refined metal, the lead alone enters the white lead, which flows continuously from the cell, leaving behind even the minute amounts of other metals contained In the anode. The composition and character of the white lead are under close chemical control during Its production la the cell. The white lead Is next washed and dried mechanically under the same close supervision and Is finally pulverized and barrelled for market. The standard package Is a barrel of 600 pounds net weight. These ere loaded Into box cars and bound into a compact unit with atsel straps to avoid damage In ahlpmmit. Tlgure 4. The propertlee of Anaoonda White Lead are as striking as the process which produces it. Its extras purity and brilliant whiteness are linked with exceptional hiding and covering poser and smooth working quailtlas. Thee# properties have created a wide dmcand for Anaconda White Lead and ahlpmsnta ranging from a few pounds to many esrlosds are mads from the Bast Chicago Plant. The product Is valuable and saally damaged, shipments s\*s as thoaa to tha Pacific Coast via Atlantic porta and tha Panama Canal, require prompt end careful handling to avoid delay and lose. The superior transports'.`.rc facilities at East Chicago are a decided adnantage to both the producer and user of Anaconda White Lead. SROOI171
