Characterization and Beneficiation of Iron Ore Tailings by ...

2015-10-20  In the present paper, an attempt has been made to beneficiate iron ore tailings by selective flocculation using guar gum and starch as flocculants along with sodium hexametaphosphate (SHMP) as the dispersant. 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.

Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the low-grade phosphate ore is, hence, of great necessity.
