| Abstract: |
| In order to recover copper and iron from a Tibet High-iron copper ore, compared the magnetic separation first then flotation test plan to flotation first and then magnetic separation. The process of flotation first and then magnetic separation was chosen as the best. Further tests and to determine the agent system, the grinding fineness was -0.074 mm accounted for 80%, lime dosage was 4000 g/t, the amount of sodium silicate was 1000 g/t, butyl xanthate dosage was 120 g/t, made the copper grade of 21.61%, recovery rate of copper is 93.89% of the copper concentrate with the iron grade of 55.95%, recovery rate of iron is 38.86% iron concentrate. The results of the flotation are copper concentrate with Cu grade of 21. 61% and recovery of 93.89%, and iron concentrate with Fe grade of 55.95% and recovery of 38.86%. |
