Copper Ores Sulfidic Crusher- Xpart Mining Machinery

Copper Copper Production Repository. Sulfidic copper ores are too dilute for direct smelting. Smelting these materials would require too much energy and very large furnace capacities. The copper ore coming from the mine (0.5 â€" 1 % Cu) must be concentrated by beneficiation. The valuable minerals like chalcopyrite are intergrown with gangue.
