Nickel recovery reached up to 35% and copper achieved 10% during column bioleaching, with base metal extraction increasing substantially at higher operating temperatures.
Assessment using column bioleaching followed by cyanidation treated chalcopyrite and pentlandite ore, employing acidophilic microorganisms across a 140-day test period.
Highlights suggest that bioleaching assists cyanidation by raising platinum yields up to 40%, whereas recovery of palladium remains mostly unchanged across conditions.
