摘　　要：从品位低、组成复杂、伴生钼、铜矿物的复杂铋矿石中浸出金属铋,采用常规搅拌浸出法在常温常压下进行浸出,讨论了酸度、FeCl3用量、浸出时间、浸出剂用量等对铋浸出率的影响。实验结果表明:用FeCl3浸出金属铋,铋的浸出率可达95%以上。Leaching of bismuth from low grade and complex bismuth ores contained with molybdenum and copper was studied, and effect of acidity, ferric chloride concentration, leaching time and leaching agent consumption on bismuth leaching rate was investigated. Result showed that leaching rate of bismuth could be reach 95%.
