Arsenic removing method for arsenic-containing smoke dust |
| abstract |
A method for removing arsenic from arsenic-containing smoke dust comprises the following steps of 10-20% of arsenic, 20-30% of tin, 3% of indium and 5-8% of lead; the dearsenization method comprises the steps of alkaline leaching of arsenic-containing smoke dust, cooling and crystallizing of leachate, recovery of lead from crystallization mother liquor and the like. The invention can effectively separate arsenic from tin and indium in arsenic-containing smoke dust and can produce sodium arsenate products. |
