Bioleaching: metal solubilization byanisms FEMS

Abstract. Bioleaching is a simple and effective technology for metal extraction from low grade ores and mineral concentrates. Metal recovery from sulfide minerals is based on the activity of chemolithotrophic bacteria, mainly Thiobacillus ferrooxidans and T. thiooxidans, which convert insoluble metal sulfides into soluble metal sulfates.Non sulfide ores and minerals can be treated by
