摘　　要：以热镀锡在镀锡过程中产生的含锡烟尘为原料,采用盐酸浸出热镀锡烟尘,在盐酸浓度为125 g/L、浸出温度为75℃、液固比为5∶1、浸出时间为100 min的优化条件下,Sn、Zn、Cu的浸出率分别为97.36%、99.03%、99.98%。Based on hot tinning line in the process of tin plating, tin flue ash was used as the raw material which was treated with hydrochloric acid leaching. The optimum conditions was obtained under hydrochloric acid concentration of 125 g/L,leaching temperature of 75 ~C ,liquid-solid ratio of 5：1 ,leaching time of 100 minute. The leaching rates of Sn,Zn and Cu are 97.36% ,99.03% and 99.98% ,separately.

关 键 词：热镀锡烟尘 盐酸浸出 浸出率
