| Abstract: |
| With dusts containing antimony as raw material, the cubic crystal antimony trioxide was recovered by the processes including leaching in hydrochloric acid, antimony powder reduction, sodium carbonate-neutralization, and hydrolysis with EDTA as an additive in ammonia. The influences of leaching temperature, leaching time, hydrochloric acid concentrate, and ratio of liquid to solid on the leaching rate of Sb, and the molar ratio of SbCl3 to EDTA on the crystal of the antimony trioxide product were investigated. The results indicated that the leaching rate of Sb was 98.50%, the recovery of Sb was 90.35%, and the purity of product with cubic crystal antimony trioxide was 99.5%. |
