【摘要】 选用了耐砷能力强、具有分解硫化矿能力的氧化亚铁硫杆菌1s、1号和马兰3种菌株作为实验用菌,对DBF矿样做氧化浸出实验,就其氧化过程中砷含量、pH变化和金的最佳浸出条件均做了详细的研究。给出细菌氧化金矿过程随时间变化的规律及金的最佳浸出条件。更多还原

【Abstract】 Three Thiobacillus ferrooxidans strains with strong arsenic resistance and capacity of sulfide ore decomposition,namely M1s,1# and Malan,were used for a microbial oxidation and leaching experiment on DBF ore from Shimian County,Sichuan Province.The arsenic content and pH change in the microbial oxidation process and the optimum leaching conditions of gold were studied intensively.The change of the microbial oxidation process with time and the optimum leaching conditions of gold are given in the paper.更多还原
