Handling guide for copper concentrate in bulk

Handling guide for copper concentrate in bulk Although copper occurs naturally in a pure state, it's primarily mined from the minerals chalcopyrite, bornite, and malachite. Copper ore is extracted form the earth, then converted into copper concentrate, which is then roasted, smelted and converted into refined copper.
