PLEASE ADDRESS ALL COMMCNTCATlOXS TO THE COMPANY Ea s t Ch ic a g o ,In d l a n a Ani from bA ujmmtrr REFevrve DEPARTMENT Noveafcer 14th, 1930 Mr. Frederick Laist, General Metallurgical Manager, Anaconda Copper Mining Company, Hoorn 1720 - 25 Broadway, New York, N. Y. Dear Ur. Laist:- The Bast Chicago Chanter of Conxnerce will publish on December 10th, their Annual P.eriew Number, This particular issue will be devoted to the transportation facilities and advantages at Bast Chicago to its Industries. They have requested each Industry to prepare a brief article outlining their use of the local transportation facilities in connection with the operationa at Bast Chicago. The attached write-up has been prepared along this line and la submitted for your approval. I understand that Mr. Thayer may not he In New York during the week ending Novaaber 22nd. The Chamber of Conaerce desires to have approval of the final write-up not later than November 19th. OBj/a CC: Mr.B.B.Thayer Did. / N10003 PNYC00000023 The operations of the International Lead Refining Company and the Anaconda Lead Products Company at Bast Chicago represent the final bringing into marketable form and the distribution of materials that hate originated at far distant places. No materials of local origin enter Into the product or take any essential part In the operation, other than fuel and a small amount of fluxing material. Comparatively little of the final product la consumed In local industries. Good fuel, labor and suitable fluxes are obtainable on satisfactory terms In East Chicago, however, numerous other localities could offer equal advantages in fulfilling Ihese requirements; - it is principally as a center of transportation and distribution to all parts of Ihe UU1 ted States that East Chicago Is well adapted for the location of this Industry. Ihe Anaconda Copper Mining Company's production of lead la derived from the treatment of the complex lead-copper-zinc ores of the Western Chi ted States, the majority of these ores contain the three metala mentioned In the form of sulphides, and In addition recoverable amounts of gold and silver. The ores are first concentrated by flotation, producing three or more products, one of which la a lead concentrate, containing the greater part of the lead and silver from the ore, with small amounts of the other metals as Impurities. The complete separation of zinc and lead by concentration Is difficult and a certain amount of the lead from the ore Is contained In the zinc concentrate. Ihe lead concentrate Is smelted at the plant of the International anelting Company at Tooele, Utah, an Anaconda subsidiary. Ihe lead and silver are recovered in the form of a "bullion" ^containing approximately 98^ lead, 60 oza. silver per ton and snail percentages of antimony and other Impurities. Thla bullion Is shipped to the International Lead Refining Company at East Chicago for refining. N10003.01 PNYC00000024 Sheet #2 v The zinc concentrate Is treated at the Anaconda plants at Anaconda and Great Falls, Montana, for the production of electrolytic zinc. Tbs lead remains In the residue after the extraction of the zinc. This residue Is smelted at the East Helena plant of the American Smelting end Refining Company and the resulting bullion, similar to Tooele Bullion In analysis, Is shipped to East Chicago for extent a custom refinery for lead bullion purchased from other sources. Lead residues and drosses from all plants of the Anaconda company are treated, and limited quantities of scrap battery plates, lead drosses, and secondary materials are purchased. The plant Is a Parkes process lead refinery of 96,000 tons' annual capacity, producing comnon desilverized pig lead, antlmonlal lead, and dors' bullion. Three railway lines enter the plant - the Indiana Harbor Belt Railroad, the Baltimore & Ohio Chicago Terminal Railroad and the Pennsylvania Railroad. The lead bullion produced at Tooele, Utah Is molded Into rectangular blocks weighing 4 tons each, loaded into open gondola cars and shipped by rail to East Chicago. At the Refinery the blocks are unloaded with tongs by an overhead crane, as shown In Figure 2, and are melted down In kettles holding 135 tons of molten metal. The antimony Is separated from the lead and silver and Is concentrated and placed In marketable form as an alloy with lead, known as Antlmonlal or "Hard" Lead. This Is cast Into 75 pound pigs and loaded into box cars for shipment. PNYCO0000025 w Sheet #3 The addition of antimony hardens and Increases the physical strength of lead, and gives it the property of producing castings of beautiful sharpness and fidelity. Antlmonial lead is used In the manufacture of storage batteries, bearing metals, type metal, ornamental novelties and a great variety of other applications. The sliver and gold are removed from the lead and, In the form of an alloy of the two metals known as dore' bullion, are shipped by express to the Harltan Copper Works at Perth Amboy, New Jersey, an Anaconda subsidiary. Here they are separated electrolytlcally and placed In marketable fora. The lead, freed of Impurities, Is cast Into 96'pound pigs, loaded Into box cars and shipped. Figure 3. The applications of lead are extremely varied and Include Industries In all parts of the United States; notwithstanding this fact the plants producing refined lead are comparatively few in number and transportation facilities for raw material and finished products are essential factors in their operation. One of the most important applications of lead Is In the production of White lead for use In paint. Here again the elements entering Into the product have little to do In determining the best location for Its manufacture. White lead Is a basic carbonate of lead, containing lead, water and carbon dioxide; no materials in any way peculiar to Hie Calumet Region enter into its production, however the product is distributed to paint manufacturers In all parts of the United States, and In the facilities that it affords for such distribution East Chicago is pre-eminently fitted for the location of this Industry. PNYC00CC0026 Sheet #4 Anaconda White lead la an exceptionally pure white lead produced hy a unique Electrochemical process developed by the Anaconda lead Products Company 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 lindberg Beacon. Refined lead for the white lead process la cast in rectangular anode plates at the Refinery and is delivered to the White lead Plant by a small industrial railway Joining the taro 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 in 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 are loaded into box cars and bound into a compact unit with steel straps to avoid damage In shipment. Figure 4. The properties of Anaconda White Lead are as striking as the process which produces It. Its extreme purity and brilliant whiteness are linked with exceptional hiding and covering power and smooth working qualities. These properties have created a wide demand for Anaconda White Lead and shipments ranging from a few pounds to many carloads are made from the Seat Chicago Plant. The product is valuable and easily damaged, shipments such as those to the Pacific Coast via Atlantic ports and the Panama Canal, require prompt and careful handling to vold delay.and lose. The superior transportation facilities at East Chicago are a decided adwantage to both the producer and user of Anaconda White Lead. PNYC00000027 PNYC00000028 PNYCOOOOOC29 PNY COC000030
