摘要
Alkaline sulfide oxidation process for treating refractory sulfide ore or concentrate particles enriched in a metal to be recovered comprising stages in which refractory ore or concentrate particles are surface-oxidized in an alkaline oxidation step in alkaline liquid phase with calcium hydroxide forming an alkaline slurry, which slurry is further mechanically activated to remove passivating coatings from the surface oxidized refractory ore particles.
