Bioleaching technology has developed rapidly today, because different bacteria has different advantagesa, the mixed bacteria may increase the leaching efficiency, so using mixed bacteria to oxidize ores has become one of hot research today. It is well known that Thiobacillus ferrooxidans(T.f) play an important role in mineral bioleaching, and in some conditions Thiobacillus thiooxidans(T.t) was investigated to enhance the bioleaching ability of T.f. Pyrite often coexists with many other minerals and plays a...
