Used Mobile Copper Ore Crushing Equipment Price
Ore will be processed using both milling and heap leaching technology. Copper, silver, and molybdenum will be recovered by grinding and froth flotation, with the principal recovered minerals being the copper sulfide minerals (bornite, chalcocite, and chalcopyrite) and the molybdenum sulfide mineral (also referred to as “moly”). Copper sulfide mineral concentrate (the end result of the milling process) produced at the mill facility will be loaded into highway haul trucks and transported off site to a copper concentrate smelter and metal refinery. Molybdenum concentrate produced at the mill site will be bagged and/or drummed and loaded onto trucks for shipment to market. The design basis for the sulfide ore processing facility is 75,000 dry tpd (dt/d) or 27,375,000 dry tons per year (dt/y).
separating minerals by floatation
The floatation process can separate a desired mineral such as copper, nickel, molybdenum, or zinc from ore. Floatation can separate the desired mineral from waste materials or from another mineral.The process starts with crushed ore. A ball mill receives the crushed ore and reduces its particle size to the consistency of sand. Next, the ground ore from the mill often travels as a high-solid slurry to a cyclone. The cyclone separates fine particles from heavier particles, which return to the ball mill for further grinding. The cyclone overflow continues on to a series of floatation cells that separate the desired mineral from other materials.
Primary crushed ore will be stockpiled on the ground in a covered ore stockpile. A reclaim tunnel will be installed beneath the stockpile. Ore for the grinding circuit will be withdrawn from the coarse ore reclaim stockpile by apron feeders installed in the reclaim tunnel. The feeders will discharge to two conveyor belts installed in series which will in turn discharge to the grinding mill.
