| Abstract: | Experimental studies were carried out to recover iron resource from copper tailings by using a combined process of beneficiation and metallurgy. The results show that, the valuable iron resource can be reclaimed using a flowsheet consisting sequentially of a high intensity magnetic separation (HIMS) for preconcentration, a roasting and a low intensity magnetic separation (LIMS). Under the following conditions, including HIMS with the grinding fineness of -0.06 mm 90% and magnetic field intensity of 0.8 T, roasting at 800 ℃ for 20 min, and LIMS with the grinding fineness of -0.06 mm 90% and magnetic field intensity of 0.12 T, the experiment by using the combined process produced an iron concentrate grading 58.38% Fe at 81.11% recovery, showing an obvious iron extraction effect. |
