25/08/2018· 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.
