| Abstract: |
| The pourbaix diagrams of Sb-S-O system were drawn by thermodynamic calculations software FactSage6.2 .Effects of reaction temperature,oxygen-enriched concentration and reaction time on oxygen—enriched volatile bath smelting of stibnite concentrate were investigated. The optimum conditions is determined as follows：reaction temperature 1200℃,reaction time 1h and oxygen-enriched concentration 80%. Under above-mentioned conditions,content of antimony in slag is as low as 0.33%。 |
