Abstract

Studies on the autoclave oxidation of nickel sulfides mainly consider the behavior of fused nickel sulfide, which is similar in composition to heatherwood Ni3S2. Only a few have highlighted the kinetics of dissolution of nickel monosulfide NiS, one of the main components of various intermediates of nickel production: anode sludge, nickel sulfide concentrate obtained by precipitation with hydrogen sulfide, intermediate phase of autoclave dissolution of nickel concentrate flotation of copper-nickel feinstein...
