  • Characterization and Beneficiation of Iron Ore Tailings by

    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 gangueIron ore tailings (IOTs) are a form of solid waste produced during the beneficiation process of iron ore concentrate In this paper, iron recovery from IOTsRecovering Iron from Iron Ore Tailings and PreparingBeneficiation of iron ore United States Patent Abstract: Iron ore is beneficiated using separation steps based on mineral composition without the use of separation steps based entirely on size In a preferred sequence of steps the iron ore is passed from a ball mill through a magnetic separator where low iron content tailings areBeneficiation of iron ore United States Steel Corporation
