| Abstract: |
| Antimony sulfide slag from antimony industrial processes was treated by vacuum evaporation to recover antimony based on characteristics of antimony sulfide slag and theoretical analysis. Effects of particle size of materials, system pressure, evaporation time, and evaporation temperature on evaporation ratio of antimony sulfide slag were investigated. The results show that evaporation ratio is 27.9% and antimony content in distilland reduces to 0.2% with antimony separation efficiency of 98.6% under the conditions including particle size of 0.106~0.075 mm, evaporation temperature of 923 K, evaporation time of 30 min, and system pressure of 50 Pa. |
