| Abstract | Mechanism and kinetics of leaching of copper-nickel matte with a model oxidizer and with chlorine are studied in laboratory tests. Influence of Redox potential on extraction of nickel and copper into solution and oxidation of sulfides into sulfates is established. Figures on precious metals extraction into solution are assessed. |
