摘要
试验考察了氯化剂添加量、氯化温度、氯化时间等因素对Au、Ag挥发率的影响。试验结果表明,当氯化温度为1 200℃、氯化剂添加量为7%、氯化时间为2 h时,Au挥发率可达到98%,Ag挥发率可达到88%。
The effects of process conditions have been investigated, such as add quantity of chlorinating agent, chlorinating temperature, chlorinating time. The test results show that when the chlorination temperature is 1 200℃, the chlorinating agent is added in 7%, and the chlorination time is 2 h, the Au volatilization rate can reach 98%, and the Ag volatilization rate can reach 88%.
