Copper Concentrate Flotation Process

The mining process - Copper | Mount Isa Mines

The greenish powder that remains once the water content of the froth has evaporated is copper concentrate. But it's not pure copper yet, it's a copper iron sulphide, made up of about 35 per cent pure copper. Now, it's ready for smelting. Copper concentrate is fed into the ISASMELT furnace, where it is heated to 1185 degrees Celsius.
