| Abstract: |
| Feasibility to enrich rhenium from copper pyrometallurgy waste acid by selective precipitation was studied. The results show that precipitation rate of Cu, Re and As is 99.10%, 99.95% and 6.43% respectively under the optimum conditions including precipitant dosage of 4 g/L, precipitation temperature of 60 ℃, and precipitation duration of 1 h. Re content in rhenium-rich slag is 2.3%. Equipment selection and benefit analysis are conducted based on the practical waste acid treatment process of one copper smelter. |
