Show j THE STORY OF TOOELE j ' ' ' . " s 1 Over the dump goes the slag By continued improvements in smelting practice at Tooele, less mineral Is lost and the miner receives re-ceives more for his product and Is enabled to produce lower- graae ores. (Editor's Note: This is the third of . series of eight articles titled "The Story of Tooele".) To Tooele goes the distinction of having operated the first custom flotation mill for the treatment of lead-zinc sulphide ores. The plant was built in 1924 by the International Interna-tional Smelting and Refining Company Com-pany in line with its program to meet the crisis that had arisen in Utah due to the dearth of oxidized ores after the end of the first World War. The plant, originally built for 500 tons daily capacity, was soon increased to 1200 tons daily. This was a revolutionary step in the nrnppsq nf RmplHne'. Tt meant that were known to exist. Ores began to pour Into Tooele from all parts of Western United States, which resulted in more industry, in-dustry, pay rolls, and tax money for Utah. Not content with being dependent depend-ent upon ores from the outside to keep its smelter and mill in operation, opera-tion, the International Company acquired ac-quired mining ground and began actual prospecting and mining. Productive and prospective mineral ground in Bingham, Park City, Eureka, and Ophir, Utah; Mountain City, Pioche, and Copper Canyon, " Nevada, was acquired. During normal years In the mining min-ing industry the company, through it.fl riivfirsifiprt minine-. milling find before going to the smelter, ores would be milled, a process likened to flour milling, separating the chaff from the wheat. It ,also meant that the zinc could be separated sep-arated from the lead and that the. miner could be paid for the zinc as well as the lead contained in the ores that his mine produced. Naturally, this revolutionary development de-velopment proved a boon to mining in Utah and the West, as large deposits de-posits of sulphide lead-zinc ores smelting of copper ores and silver, lead, and zinc ores, pours into the channels of industry throughout Utah approximately $20,000,000 annually an-nually in the form of pay rolls, supply sup-ply purchases, construction, railroad rail-road freight, taxes, etc. Normally the company employs an average of 2000 workers and an equal number num-ber are furnished employment indirectly. in-directly.
