The high-grade copper concentrate can be obtained by the coarse grinding, roughing, scavenging of copper ore, then grinding and concentrating of coarse concentrate. Classification of copper ore Due to the different types of ore, the nature of the ore is also different, so the beneficiation process needs to be customized.
