The beneficiation process of nickel ore,copper-nickel,

Therefore, copper-nickel separation technology is an important topic in copper-nickel ore beneficiation. 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,Cobalt and Nickel Separation in Nitric Acid Solution by,,Cobalt and Nickel Separation in Nitric Acid Solution by Solvent Extraction Using Cyanex 272 and Versatic 10 M.Z.
