Copper mine beneficiation development history of USA:
Copper mine is the larger resource of USA, with the mining technology greatly development in recently years, many investors want to invest this copper beneficiation pant and flotations.
Copper is increasingly recovered by solution, or hydrometallurgical, methods. These include dump, heap, and vat leaching techniques, as well as underground (or in situ) leaching methods. Each of these methods results in a pregnant leach solution (PLS). Copper is recovered from the PLS through precipitation or by solvent extraction/electrowinning from 1988.

Copper mineral concentrate, the product of flotation, is then sent to a smelter for processing. The waste material or tailings from this operation is sent to a tailings pond for disposal. Copper concentrates exiting the flotation circuit contain 60 to 80 percent water. Dewatering the concentrate in a thickener, then in disc or drum filters for final dewatering, produces a relatively dry product ready for further shipping and processing.Liming heavy industry is a larger manufacturer and supplier for best quality copper mine beneficiation machines.

The copper ore crushing machine include jaw crusher, impact crusher, cone crusher, VSI series crusher. The jaw crusher is usually used as primary crushing. The size of copper ore can be crushed to 20mm. The scope of the motor power is 37-200(KW)，and the output is from 12t/h to 800t/h. For different requirement, we will provide different choices. Cone crusher is widely suitable for artificial sand making. The hard materials which have been crushed by the jaw crusher will be sent to cone crusher. The special designs make hydraulic cone crusher is widely used to crush the hard stone.
