Copper Sulfide Flotation - Mineral Processing and Metallurgy

The Ball Mill in closed circuit with a Spiral Classifier discharges the pulp at about 60% minus 200 mesh. The Ball Mill is equipped with a Spiral Screen on the discharge for removal of any tramp oversize, worn grinding balls, and wood chips from the circuit. Copper Sulfide Flotation CircuitCopper Flotation - Mineral Processing and MetallurgyThe flowsheet in this study illustrates the modern approach to porphyry copper treatment throughout the industry. Each plant will through necessity have somewhat different arrangements or methods for accomplishing the same thing and reliable ore test data are used in most every case to plan the flowsheet and design the mill. Flotation of Copper ...Grinding Circuit - an overview ScienceDirect TopicsThe high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many low-grade, high-tonnage operations such as copper and gold ores feasible. Future circuits may see increasing use of high pressure grinding rolls Rosas et al., 2012 .
