| Abstract: | A beneficiation test was carried out to treat a copper-iron ore in Sichuan. A flotation and magnetic separation approach was adopted. Copper minerals were collected using a flowsheet consisting of one stage of roughing, two stages of cleaning and one stage of scavenging. Magnetic minerals were collected using a flowsheet consisting of one stage of roughing and one stage of cleaning, with the middlings re-ground and reprocessed. As a result, it is shown that 90.38% Cu was recovered to the as-reclaimed copper concentrate grading 22.50% Cu, and 88.20% Fe was recovered to the iron concentrate grading 60.20% TFe, indicating that the copper and iron resources therein were effectively recovered. |
