According to Hourn et al. (2005), ultrafine grinding of sulfide minerals to particle size of 80% passing 8–12 μm will eliminate mineral passivation by sulfur precipitates, as the leached mineral will disintegrate prior to the precipitate layer becoming thick enough to passivate it. The oxygen used for oxidation is injected into the base of ...
