Extraction of Copper from Copper pyrite Reference Notes

The principle ore of copper is copper pyrite and copper is extracted from this ore. The different steps in extraction of copper are Crushing and Concentration The ore obtained from mines are broken down into small piece by jaw crusher and then pulverized. The ore being sulphide ore is concentrated by froth floatation process.
