BENEFICIATION OF COPPER Et NICKEL ORES

2011-8-5  BENEFICIATION OF COPPER Et NICKEL ORES COPPER ores in India are of low grade like any other deposits elsewhere in the other parts of the world. Chalcopyrite is the most common and usual copper mineral; the other minerals have been chalcocite, covellite, bornite, which are all copper and copper-iron sulphides while enargite, tetrahedride and

Intensifying the Beneficiation of Norilsk Copper-Nickel

It is established experimentally that radiation treatment of Cu-Ni ore permits directed change in the granulometric composition of the comminution products, with simultaneous increase in the mineral opening coefficient by a factor of 1.5-2 and improvement of the technological beneficiation characteristics. In the Cu-Ni flotation cycle, the extraction of copper and nickel increases by 7.8 and

2021-10-28  Copper ore beneficiation methods. Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm.
