The bioleaching of different mineral sulfide concentrates with thermophilic bacteria (genus Sulfolobus) was studied to determine optimal conditions for metal recovery. The research focused on the influence of stirring methods and pulp density on dissolution rates. Findings revealed that pneumatic stirring was more effective at lower pulp densities, while orbital stirring yielded better results at higher densities. A comparative analysis of three differential concentrates, one mixed concentrate, and one global concentrate highlighted the role of bacterial activity in copper and iron extraction, with zinc dissolution occurring primarily through an indirect mechanism activated by copper ions. Additionally, galvanic interactions among various sulfides were found to enhance the selective bioleaching of specific phases, such as sphalerite and chalcopyrite, leading to high metal recovery rates. However, the effectiveness of these galvanic couples varied depending on the types of concentrate used, indicating the need for tailored approaches to bioleaching in mineral processing.
