| Abstract: | When compared to the traditional mineral oxidative processes, biooxidative process has a bright prospect in industry with the characters of economic, environmental friendly. The new technique of biohydrometallurgy will bring novel opportunities and challenges to recovery the valuable metallic elements from the low grade refractory sulfides. The parameters of biooxidative processes all over the world on bacteria collected and the adaptation treatment, optimization for culture medium, inoculation ratio, optimum temperature and acidity in bioleaching, mineral particle size, slurry density of leaching system, and arsenic speciation in leaching solutions were reviewed in details. |
