The acidic leaching solution dissolves the remainder of the zinc oxide along with metallic impurities (arsenic, antimony, cobalt, germanium, nickel, and thallium). Insoluble zinc ferrite, formed during concentrate roasting by the reaction of iron with zinc, and the lead and silver remain in the leach residue.
Ultrafine Pyrrhotite Concentrate. Ultrafine grinding is used to liberate gold finely disseminated in metallic sulfides. KCGM is the first gold mine using ultrafine grinding followed by cyanidation (Ellis and Gao, 2002). The gold sulfide concentrate is grind with an IsaMill to a P80 of 10–12 μm.
