Mineral Processing: Comminution. The first stage of copper processing is the comminution, which is carried out to liberate the copper-bearing minerals from the gangue by reducing the ore particle size. Firstly, explosions are made in the mine to crack the rocks, generating various fragments of ore. Then, these large fragments are …Web
