采用两株氧化亚铁硫杆菌对一种含砷金精矿进行了不同充气条件的氧化脱砷和氰化提金试验，结果表明微生物的活性是影响脱砷效果的关键。同时，只有脱砷率超过５０％以后，才能明显改善矿石中金的氰化浸出指标。
Two strains of Thiobacillus ferrooxidans were used for oxidative arsenic removal and cyanidation gold extraction of a gold concentrate containing arsenic under different aeration conditions. The results showed that the activity of microorganisms was the key factor that affected the arsenic removal efficiency. At the same time, cyanide leaching index of gold in ore can be significantly improved only after the arsenic removal rate exceeds 50%.
