| Abstract: |
| The characteristic of the refractory oxidized copper ore is the high oxidation ratio, the high combination ratio, the target is bad by flotation. Based on this characteristic and in order to improve the grade of copper concentrate, two schemes of agitation leaching - cementation - flotation and agitation leaching - solvent extraction - electrowinning are proposed. Results show that the scheme of agitation leaching - cementation - flotation is the best. The copper concentrate grade of 35.81% and the recovery of 92.92 % are obtained. |
