How is copper mined and processed? - AskingLot
How is copper mined and processed? Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides. The oxides are smelted to produce matte, which then undergoes several refining processes.
