A Beneficiation Study on a Low Grade Iron Ore by Gravity and Magnetic

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 …

DRY MAGNETIC SEPARATION OF MAGNETITE ORES

The relevance of the paper is that dry magnetic separation (DMS) is the main beneficiation method of magnetite ores. The lack of efficient industrial-grade machines and apparatus for separating fine-grained magnetite ores means that DMS is used mainly as a pre-concentration operation for fairly large classes. The aim of the research is to study the …
