摘要
采用还原焙烧-硫化钠浸出工艺解决了锑回收的问题。富锑烟尘先进行焙烧,焙烧渣经硫化钠浸出,锑的浸出率>90%,锡的浸出率<1%,锡锑分离效果较好。
The recovery problem of antimony is resolved by fiched with antimony shall be roasted, the roasted slag shall be reached reduction roasting-sodium sulphide leaching process. The fume en- by sodium sulphide, and the leaching rate of antimony 〉90%, the leaching rate of tin 〈 1%, the separation effect of tin and antimony is good.
