【摘要】 通过摇瓶试验研究混合硫杆菌浸出黄铜矿尾矿砂,并初步探讨不同矿浆质量浓度和柠檬酸质量浓度对浸提实验的影响。研究结果表明,添加柠檬酸在一定质量浓度范围内对黄铜矿尾矿砂的硫杆菌浸提有促进作用。在整个浸提实验中,浸矿效率最高达到44.8%,溶液中柠檬酸质量浓度和矿浆质量浓度都会直接影响细菌的氧化活性和浸矿效果。更多还原

【Abstract】 The effect of mixed sulphur bacilli on the bioleaching of chalcopyrite tailings in shake flask and the effect of different citric acid concentrations and slurry densities on leaching tailings are studied.The results show that the concentration of citric acid in a certain range can promote chalcopyrite tailings bioleaching,and the highest of leaching rate is 44.8%.The citric acid concentration and slurry density directly affect the oxidation activity of bacteria and the effect of leaching.更多还原
