| Abstract: |
| De-arsenic from the dust of copper flash smelting furnace was studied by pyrometallurgical method. The facts of temperature, roasting time and coke additive on de-arsenic were investigated using orthogonal experiment. The results indicated that de-arsenic rate was more than 80% and the recoveries of copper were more than 95% under the following condition: 1 100 ℃ roasting temperature, 1 h roasting time and 12% coke additive. |
