摘　　要：生物湿法冶金技术与传统矿业氧化工艺相比 ,成本低、无污染 ,具有广阔的工业应用前景。本文着重评述了国内外在浸矿微生物、培养基的优化、细菌的接种量、温度、酸度、矿石粒度、矿浆浓度、浸出液中As(Ⅲ )和As(Ⅴ )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.
