The beneficiation process of nickel ore,copper

Copper-nickel separation technology is divided into two types: copper-nickel mixed concentrate separation and high matte separation technology. Generally, the former is used for copper-nickel minerals with relatively coarse grain size and not closely related to each other, and the latter is used for copper-nickel minerals with fine grain size and densely interspersed ore.
