Show Bingham District Metal Production Up In 1941 m m mm mm II ee The Bingham district, by far the outstanding mining region of Utah, produced most of the state output of copper and gold, nearly half of the zinc and lead, and more than a third of the silver in 1941: the value of these five met' als was $82,558,340, or 84 per cent of the value of the entire state output during the year. - Utah Copper company operations opera-tions accounted for most of the gain over 1940 in value of gold and silver produced and virtually virtual-ly all the gain in value of copper produced in the Bingham district in 1941. These gains in output were attained only through an all-out effort, started before 1941 and stimulated further by the present urgent need for copper. During 1941 the company milled an average of about 83,000 tons a day at its two flotation-concentration mills. The average copper content of the ore treated was sliehtly higher than in 1940, due chiefly to the fact that a larger nortion of the ore came from the lower levels of the Bingham pit. Ore and waste were mined at a rate exceeding 188,000 tons a day. The waste rock was piled in ad-iacent ad-iacent gulches and leached there. In addition to the vast quantity of copper recovered from copper concentrates, the company recovered re-covered about 13,000,000 pounds of copper from the copper-precipitating plant at Lead Mine. The Sold, silver, and molybdenite product pro-duct on from these copper ores far exceeded that of any other nroperties in the state, and the company ranked high among the leading gold and silver producers produ-cers and second in production of mllybdenite in the United States. May 1942 the company ex-ceded ex-ceded its 1941 production schedule sche-dule and was producing copper at the rate of about 600.000.OUU pounds a year. The Kennecott Copper corporation revealed the following operating details in its printed annual report. The mine operated 364 days during 1941, and the tonnage of ore hauled to the concentrators for treatment was 16 per cent above that in 1940. The railroad congestion resulting re-sulting from this larger tonnage necessitated construction of a supplemental train - assembly yard about one mile from the main yard at Bingham. ' The Boston Consolidated property, pro-perty, owned by the Utah Copper Cop-per company, was operated under un-der lease by the American Smelting Smel-ting & Refining company. Crude copper ore was shipped direct to a smelter. The zinc and lead output of the Bingham district was produced largely by the United States and Lark mine, owned and operated by the United States" Smelting, Refining and Mining company. The tonnage of gold-silver ore and lead ore shipped for smelting smel-ting increased slightly over the output in 1940, when 13,311 tons were shipped. The tonnage of zinc-lead ores shipped for milling at Midvale in 1941 was slightly less than in 1940 and lower in zinc and lead content but higher in gold and silver. In 1941 this property was second in silver and third in gold output in the state. During the first quarter of 1942, the property showed a marked increase in zinc-lead output over the monthly average for 1941. Development work consisted of driving 560 feet of shaft and 19.731 feet of raises. The Niagara mine shipped over 12,000 tons of ore of all classes to Midvale for treatment, and most of it was zinc-lead mill ore. The Montana-Bingham Montana-Bingham Consolidated ' Mining company shipped over 7,100 tons of ore of all classes. The Utah Metal property, leased by the United States Smelting, Refining and Mining company, was the only other property active in the Bingham district in 1941 among those owned or controlled by the United States Smelting, Refining Re-fining and Mining company; small shipments of zinc-lead ore were made incident to development develop-ment of the property. The National Tunnel and Mines company operated the Apex-Delaware group from January thru July 1941 on company and lessee les-see account. The output was chiefly zinc-lead ore shipped to the Tooele 'sulfide concentrator and amounted to approximately one-half that produced in 1940. The Elton tunnel, driven by the National Tunnel and Mines company com-pany was completed in July 1941 as far as the main objective reaching the Rood shaft in the Utah Apex mine. The rest of the year was spent mainly in rehabilitation reha-bilitation of old workings and work preparatory to the extraction extrac-tion of ore. Limited production from the property was under way in April 1942; it is . anticipated that by June 1942 normal production pro-duction will have been established. establish-ed. ' The Ohio Copper company treated 341,936 tons of old tail-lings, tail-lings, containing 2,097,531 pounds of copper in concentrates; in addition, ad-dition, 422 tons of copper precipitates preci-pitates were produced. The 1000-ton 1000-ton flotation mill treated a daily average of 958 tons of tailings. A total of over 31,000 tons of ore of all classes was shipped from the Butterf ield properties to the Combined Metals Reduction Reduc-tion company concentrating plant at Bauer and the International Smelting and Refining company at Tooele, or considerably less than the output in 1940. Among other producers in the Bingham district in 1941 were the New England, Chicago, Kremlin, Krem-lin, and Colonel Sellers properties proper-ties which shipped crude ore direct di-rect tQ smelters. |
