Sep 26, 2019Currently, about 80% of global copper production is extracted from sulfide sources. Regardless of the ore type, mined copper ore must first be concentrated to remove gangue or unwanted materials embedded in the ore. The first step in this process is crushing and powdering ore in a ball or rod mill. Sulfide Copper Ores
