starch for iron ore beneficiation

During the last ten years great strides have been made, on the Mesabi range, in the practice of beneficiating low grade iron ore material. By beneficiation is meant all methods of removing impurities, and raising the iron content to a point where it can be sold in open market, the principal impurities being silica and moisture. The general processes to which low grade iron ores are amenable

Oct 20, 2015 · The mineralogical studies carried out initially indicated the presence of hematite and goethite as major iron bearing mineral phases along with quartz and kaolinite as major gangue minerals. The selective flocculation process showed that the Fe grade could be enhanced from 58.24 to 65.32 % Fe using starch as flocculant with a recovery of 62.08 %
