| Abstract: |
| Precipitation process optimization and improvement method of pretreatment of cuprous telluride sludge with copper anode sludge were introduced. The experimental results show that precipitation rate of tellurium rises from 90% to 98% above and dosage of copper powder drops from twice to 1.35 times of theoretical quantity by applying new process of reduction of cuprous telluride slag and replacement with copper powder. Plant practice proves that this new process has comprehensive economic benefit and can achieve high recovery of tellurium in solution. |
