Physicochemical laws of the atmospheric sulfuric acid leaching of the copper—nickel concentrates from the beneficiation of disseminated ores

A physicochemical substantiation is performed for the organization of a combined flotation hydrometallurgical technology for the processing of the copper—nickel concentrates from the beneficiation of disseminated ores. This technology is used instead of the traditional pyrometallurgical technology providing the production of a sulfide concentrate with a total nickel, copper, and cobalt content of 14.64% for the through extraction of (wt %) 92.2 Ni, 74.0 Cu, 95.3 Co, 91.9 Pt, 95.9 Pd, and 96 Rh to the concentrate.
