Several processes are used for extraction of same metal depending on occurrence and chemical requirements. It takes multiple steps to extract the "important" element from the ore: First, the ore must be separated from unwanted rocks. Then, the minerals need to be separated out of the ore
Extraction of copper ore. Extracting copper ore is a labor-intensive process that requires various stages and special equipment. The process begins with blasting, where explosives are used to break apart the ore so it can later be loaded into trucks and sent to crushing facilities.
The important ores of copper are copper pyrites ((CuFeS_2)), cuprite and copper glance. The copper ores are mostly found in the north of India. The extraction of copper also involves many steps. The ore used for extraction is copper pyrites, which is crushed, concentrated and then heated in the presence of air.
