Optimization of reagent dosages for copper flotation using

In the Sungun Concentrator Plant, the crushed ore is fed into a semi-autogeneses (SAG) mill to produce a product with K80 = 3 mm (Fig.1). The SAG mill products are then transferred to the two ball mills, where the ore is ground to a level of K80 = 80 μm. Lime, collectors of Z11 and AP407 are added to the ball mill feed as well. Then the

Copper extraction Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
