| Abstract: | A new technology of arsenic removal for treating arsenic-rich lead anode slime by volatilization roasting in steam condition was developed in this paper.The influence of reacting atmosphere,roasting temperature,and roasting time on the volatilization rate of As was studied systematically.The results of roasted sand experiments under the optimal conditions showed that the volatilization rate of As was more than 87% and the arsenic content in the roast was below 3% in steam condition.The phase transformation and reaction mechanism in the process of roasting for arsenic removal was also discussed by means of XRD. |
| Keywords: | metallurgy arsenic-rich lead anode slime roasting in steam condition arsenic removal |
