氯化钠—次氯酸钠法从氰化渣中回收金
Sodium Chloride-Sodium Hypochlorite Method for Gold Recovery from Cyanide Residue
【摘要】 以氯化钠为溶剂,加入适量次氯酸钠,考察了液固比、浸出温度和时间对氰化渣中金浸出率的影响。结果表明,在下述最优试验条件下,金浸出率可以达到41%以上:浸出温度50℃、浸出时间3h、液固比4。
【Abstract】 The effects of ratio of solid to liquid,leaching temperature and time on the gold leaching rate were studied by adding a proper amount of sodium hypochlorite with sodium chloride as solvent.The results show that the gold leaching rate is above 41% under the optimum conditions including leaching temperature of 50 ℃,leaching time of 3 h and ratio of solid to liquid of 4.
