| Abstract: |
| High As and Sn bearing anode slime were treated by alkaline roasting and leaching. The effects of mass ratio of soda to anode slime, roasting temperature, roasting time, L/S, leaching temperature, and leaching time on leaching efficiency of metals were investigated. The results show that leaching rate of As is 95.2% and As content in leaching slag is 0.5% below under the optimum conditions including mass ratio of soda to anode slime of 0.9, roasting temperature of 600 ℃, roasting time of 2 h, L/S=3 mL/g, leaching temperature of 80 ℃, and leaching time of 2 h. Other valuable metals in anode slime are relatively enriched for further recycling. |
