How much metal does the ore contain? « World Ocean Review

One example is copper. Copper ore does not contain pure copper, but either a copper-sulphur-iron compound (chalcopyrite) or a copper-sulphur compound (chalcocite). The metal must first be separated from such minerals by means of multi-step metallurgic processes. In many cases these processes are so complicated.

Sources of Copper Ore | Copper Development Association of South .

Mining. Dissolved copper from deep underground cools to form the primary orebody. To a large extent, copper oxide and sulfides are naturally separated in nature. As such, once mined the processing of the ore generally does not need to separate the oxides and sulfides.

Introduction to Mineral Processing - Chevron Phillips Chemical

The concentrate, which is now approximately 30% Cu and 0.35% Mo, is pumped to the molybdenum plant where the molybdenum disulfide is separated from the copper sulfide. Chemicals referred to as depressants are added to the pulp to reduce the flotation of the copper minerals while allowing the molybdenum minerals.
