)) decreases from 530 to 3 mg/L and the mass ratio of copper to nickel (RCu/Ni) in the residue reaches above 15 when the MnS dosage is 1.4 times the theoretical value Dt,MnS (Dt,MnS=0.74 g) and the pH value..., complete copper separation from nickel solution requires that the mass ratio of copper to nickel in the residue (RCu/Ni) should be larger than 15. In this case, the residue can be sent for copper......

and crystallization of iron rich liquid at low temperature. Copper is extracted from iron leaching residue by acid oxidation leaching process, and CuSO4·5H2O is obtained by crystallization of copper rich liquid after purification. At the same time, the monomer dissociation of diamond and WC in copper leaching residue was realized, through gravity separation process, the diamond and WC can be separated......
