| Abstract: |
| Process mineralogy research and mineral processing experiment research have been carried out for a copper smelting slag；After primary grinding(particle size 80% -0.043 mm) and speed flotation have been carried out for the slag , a qualified copper concentrate can be obtained. By regrinding and reconcentration of unqualified rougher concentrate , another part of copper concentrate and final tailings are produced. In closed-circuit test, the copper grade of mixed concentrate can reach 29.68% with the recovery of 90.45%, and the tailings copper grade is down to 0.28%. Efficient recovery of copper from the slag can be achieved by test work. |
