摘　　要：氯化工艺中,当氯化温度为500℃,氯化时间为60 min,NaCl的用量为10%时,金、银的浸出率最高,分别为66.41%、40.18%。在上述条件不变的情况下,如果将水浸改为稀酸浸出,氰化前干磨3 min,则金、银的浸出率可以分别达到72.97%、55.41%。In the chlorination process,when the chlorination temperature is 500℃,the chlorination time is 60 min,and the amount of NaCl is 10%,the leaching rates of gold and silver are the highest,which are 66.41%and 40.18%,respectively.Under the condition that the above conditions remain unchanged,if the water leaching is changed to dilute acid leaching and dry grinding for 3 min before cyanidation,the leaching rates of gold and silver can reach 72.97%and 55.41%,respectively.
