Then wet grinding in semi-autogenous rod or autogenous ball mills takes place. Size classification takes is performed in cyclones. In the next step of beneficiation valuable minerals and gangue are separated by froth flotation of the ore pulp which exploits the different surface properties of the sulfidic copper ore and the gangue 46 .
