2018-8-25 In this paper, a sample from Tange-zagh iron mine was characterized by gravity and magnetic separation methods. The mineralogical studies showed that hematite and goethite are the main iron-bearing minerals with insignificant amounts of FeO. The results indicated that spiral separation yields higher separation efficiency than others. The combination of spiral and multi gravity

Magnetic roasting-magnetic separation converts iron oxides into ferromagnetic magnetite through reduction roasting at 500–800 °C prior to the magnetic separation. Yu et al. [ 7 ] used this method to treat oolitic hematite ore, and a concentrate with ~57% Fe content and ~90% Fe recovery was obtained.
