Show Mining-Milling Project Nears Production Stage list r&&r - ' tK View of Tintic Standard Mining Company's fluorspar mill, located southwest of Milford. Mill is now undergoing tests. Portion . A M Mill Is Completed; Tests Are Started Completion of the nw Tintic Standard Mining company's fluorspar fluor-spar mill at the Cougar mine in the Washington mining district, 65 miles southwest of Milford, marks the first step toward establishing estab-lishing Utah as a major producer j of metallurgical and chemical i grades of fluorite. The mill was completed during the past weekj and is undergoing test runs, ac-: cording to a story in the mining! section of Sunday's Tribune. j Because of the increased de. j mand for metallurgical fluorite,! wartime requirements for chemical grade fluorite, and the westward , trend in the steel business, the' Tintic Standard Mining company! optioned the Cougar property,! which was then explored by the , mining division of the U. S. bureau 1 of mines. When this work had, given assurance of at least 80,000 1 tons of ore averaging 40 per cent calcium fluorite, the company exercised its option and entered into a contract with Metals Re-j serve company for a definite! quantity of concentrate over thej period from January 1, 1944, to. March 31, 1946. Having decided to finance a mill j privately, the Tintic Standard ( company, with the cooperation of; the metallurgical division of the; bureau of mines, conducted metal- j lurgical research to determine j upon a flowsheet for a mill having j capacity to treat 100 tons of com-; pany ore and additional custom' ore per day to obtain a metallurgical metal-lurgical product with provision for the later addition ef equipment ! necessary to produce the highest' grade chemical fluorite. Cost of development and the mill has been : approximately ?175,O0O. j Chief Engineer Milton D. Paine' and Harry P. Allen, company met-i allurgist, the Western Knapp En-; gineering comany, the Western Engineering company and the Western Machinery company have designed and constructed the mill. Paine and M. H. Howes, superintendent, superin-tendent, have had charge of mine development carried on in addition ; to the exploration done by the ' bureau of mines. I The flowsheet is simple. The crushed and screened fluorspar is treated in four Pan-American jigs! which yield the concentrate and i tailings which will be stockpiled 1 for future treatment by flotation cells when the company decides to produce a chemical grade fluorite.; The concentrate is dehydrated be- i fore shipment, an important step ; in more than one respect at thej Cougar property, where water is very scarce.' The mill circuit will carry about 600 gallons and since j present supply is only 20 gallons per minute, conservation is of great importance. New sources of i water are being investigated. Power is supplied by Diesel en-, gine. The concentrate from the mill, j situated 36 miles from the nearest Ulephqpe, will be trucked to Lund of mine dump can be seen at he right. Project represents an investment of $175,000. Cut courtesy Salt Lake Tribune for shipment. Potential shippers of fluorspar to the Cougar mill include in-clude the Holt Blue Bell, the .Staats Utah and Lost Sheep mines. The New Park Mining company of Keetley plans to ship to the Cougar Cou-gar mill from the Lost Sheep prop, erty, now under development. James W. Wade, vice president and general manager of the Tintic Standard company, when interviewed, inter-viewed, stressed the handicaps of a remote location and a winter of unusual snows in development of the mine and completion of the mill, all of which was accomplished accomplish-ed under the direction of M. D. Paine, chiaf ttnginaer. |
