| Abstract: |
| Chloride–hydrolysis technology is adopted in this paper to prepare antimony trioxide from arsenic antimony fumes. After arsenic removal via acid leaching, we investigate the effect of hydrolysis time, hydrolysis temperature, and dilution ratio on antimony hydrolysis as well as the impact of dilution ratio, ammonia excessive factor, reaction temperature and reaction time on antimony oxychloride dechlorination. The result shows, the recovery of antimony can reach up to 80.99%, when arsenic antimony fumes is hydrolyzed with dilution ratio 6:1, hydrolysis temperature 25℃, and hydrolysis time 1.5h, and dechlorinated with liquid-solid ratio 1.5:1, reaction temperature 25℃, reaction time 0.5, ammonia excessive coefficient 1.5. |
