Show BULLIOKlflLLE" MILL TO START JUL! 15 To Treat 200 Tons Per Day by Use of Flotation Process. Construction work on the Bullionville mill Icing erected at Bullionvillo, about eleven miles south of Pioche, Nov., by the Prince Consolidated Alining coin-puny, coin-puny, is being rushed to completion as I rapidly as possible, according to A. At. McDonald, who is in Salt Lake on mining min-ing business. Mr. McDonald, who has 1 he contract for tho construction work and who has built practically all of the larger mills in th;- 1 in tic district, among which are the Tintic milling plant and the Utah Metals concentrating plant, said that the Bullionville mill would bo in operation by ,Jutv 15. lie also has the contract for delivering the tailings tail-ings to the mill that arc to be treated. The capacity of the new mill will be 200 1 ous per day. There are approximately approxi-mately li'0,000 "tons of tailings, one dump being located at Bullionville and the other dump eight miles away at Dry Valley. These dumps are connected connect-ed by railroad. The tailings at the Bullionville dump will be elevated to the mill by a sixteen-inch conveyor belt, 548 feet jn length. They will be delivered de-livered to the btit from a large bin in which they will be placed by scrapers. . Average samples of the tailings show that the metal content is ' per cent lead, 10 ounces in silver and $2.40 iu gold to the ton. Cost estimates show that these tailings can be treated at a good profit to the company. Inasmuch as a great portion of tho values are in the forms of carbonates and oxides, the tailings will be sent through a tube mill to cleanse them and break up the lumps and will then be treated with a sodium sulphide solution solu-tion by agitation and sulphurized. By this process the tailings are put into a form from which tho values can be recovered re-covered bv flotation. I Mr. MeTJonald leaves today for the Tiutic district and will return to Pioche on July 5. In discussing conditions at Pioche Mr. McDonald said yesterday that there was considerable activity, there and that the district was sending i out the heaviest tonnage in years. j |
