The copper-iron ore has grades of 0.58% Cu and 42.14% Fe in Anhui. According to test on raw ore, it has the characteristics of close intergrowth and fine dissemination size, which belongs to a refractory ore. The copper oxide distributes mainly at the perimeter of copper sulfide. According to the characteristics of the structure, a flow sheet of rough grinding and flotation of inter-locked particles is taken. This process can recover copper effectively, leading to the recovery of Cu increase to 70.05%.A combined technological process of high intensity magnetic separation-gravity separation is used to hematite, which achieves an iron grade of 62.34% in the final concentrate and a recovery of 65.49%.
