One such example is the iron ore sector, which involves separating large amounts of valuable iron minerals from gangue minerals. Plants processing those minerals treat many millions tons of ore every year, and most of the refinement and separation techniques used rely on bulk ore properties (density, size, magnetism) and wet processing.

In this paper, a sample from Tangezagh iron mine was characterized by gravity and magnetic separation methods. The mineralogical studies showed that hematite and goethite are the main ironbearing 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 methods showed ...
