　　熱鍍錫生產廢鐵時產出熔劑(氯化鋅)渣、錫鐵渣和油渣，其中焊錫材料錫主要以FeSn2xingtaicunzai。zuizaocaiyongjiarerongxifachanchucuxi，jinglianhoufanhuireduxiyong。qizhongrongjizhakexianyongshuijinchulvhuaxinbinghuishouliyong。rongxifayinxihuishoulvdi，xianjindougaiyongshifayejinhuohuofaronglianchuli。
 
　　濕法冶金是用濃鹽酸浸出，浸出液用鋅板置換得到海綿錫後，再經沉澱鐵、濃縮，回收ZnCl2返回利用，焊錫材料錫的回收率可達85%。火法熔煉是加入富矽鐵(75%Si)用電爐熔煉生產粗錫，錫的回收率可達95%。
