14 Kinds of Copper Ore Analysis and Beneficiation Methods
Gravity separation plays an important role in ore separation, especially for copper ore separation. The difference of specific gravity between copper ore and waste rock is the key factor of gravity separation, but the copper sulfide ore with coarse-grained embedded crystals has a larger specific gravity, which is obviously different from waste rock.
