Co-Bioleaching of Chalcopyrite and Silver-Bearing …

Chalcopyrite and bornite are two important copper minerals, and they often coexist. In this study, the co-bioleaching of chalcopyrite and silver-bearing bornite by mixed moderately thermophilic culture at 50 °C was investigated. The bioleaching results show that the extraction percentage of Cu for co-bioleaching of chalcopyrite (Ccp) and silver-bearing bornite (Bn) (Ccp/Bn = 3:1) was 94.6%.The interaction of acidophilic iron and sulphur-oxidising bacteria (A. ferrooxidans, L. ferrooxidans and A. thiooxidans) with a bornite-chalcocite ore at pH 4 and pH 2 was examined to determine the effect of secondary mineral coatings on bioleaching/copper solubilisation.Rock sample chips were suspended in the bacterial consortium for 24 h (providing a limited window for colonisation) to ...
