    Generally, copper extraction follows the sequence (see Figure below) 1. Beneficiation by froth flotation of ore to give copper concentrate (Optional partial roasting to obtain oxidized material or calcines) 2. Twostage pyrometallurgical extraction 1. smelting concentrates to matte 2. converting matte by oxidation to crude (converter or blister) copper 3.

    After the copper ore is crushed, liquid is added to make it a slurry. The slurry is a mix of valuable copper ore minerals and worthless rock, called gangue (pronounced gang). The slurry is placed in a tank and a process called froth floatation is used to separate the copper minerals from the gangue.

When the ore/lime slurry emerges from the mill, it is fed to a rake classifier. Particles that are too large to pass from the classifier are returned to the mill, while the overflow is discharged to flotation cells.
