| Abstract: |
| The arsenic-copper slag which was come from the purification process of copper electrolytic solution,was pressure leached and the leaching solution was purified,the copper was enter into the sequential process as semifinished products,during the process about 98% of copper and 95% of arsenic was leached,while antimony and bismuth was mostly precipitated as the slag,and the slag rate is about 3%~5%.The leaching solution is purified,it contains less than 1g/L of As,the arsenic is removed in the form of calciu... |
