| Abstract: | Based on the characteristics of close intergrowth and fine dissemination size of the copper-iron ore in Qinhai, a flowsheet of fine grinding-low intensity magnetic separation- desliming-flotation was adopted to reclaim synthetically copper and iron, and a iron concentrate containing 63.85% Fe with a recovery of 14.51% and a yield of 8.60%, and a copper concentrate with a Cu grade of 18.54%, a recovery of 69.33% and a yield of 4.66%, can be obtained. |
