The copper ore of a copper mine in Zimbabwe is mainly copper-bearing pyrrhotite and high-copper skarn ore. The copper grade of the original ore is 1.25%, and its iron grade is 30.73%. The copper minerals in the ore are mainly chalcopyrite, followed by porphyry, and a small amount of chalcocite, covellite, malachite, etc.

Copper Floatation Process Application 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
