Copper Smelting Chemistry Tutorial
A copper ore is a mixture of copper minerals and other materials in the rock called gangue, from which it is economically viable to extract the metal. A typical copper ore contains between % and % copper. A high grade ore produces a high yield of metal. A low grade order produces a low yield of metal.
