The selective leaching of tin anode slime was extremely important in the process of the recovery of tin anode slime. With the successful leaching, the efficiency of value metals recycling was elevated obviously. Hence, the pretreatment of tin anode slime was studied in this paper by using the environmental technology and hydrometallurgical approach to achieve the goal of valuable metal recovery from traditional waste tin anode slime. It is worth noting that there are a large amount of value metals including Sn, Sb, Bi, Cu and Ag in the tin anode slime. The results indicated the optimal conditions of leaching process are 3.0 M HCl with 0.1M NaClO3 and liquid-solid mass ratio of 30 ml/g in 30 minutes at 45 degrees of Celsius and about Sn 85.32%, Sb 96.93%, Bi 97.63%. Meanwhile, silver and copper were all leached out by HCl solution in the leaching of tin anode slime.
