  Characterization and Beneficiation of Iron Ore Tailings by …

  20151020 · 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 …

  Driving investments in ore beneficiation and scrap upgrading …

  2021520 · An estimation of the beneficiation costs of ore and upgrading cost of scrap was made and the costs were compared with the benefits. The overall conclusions are as follows: The loss of iron units in ore beneficiation is compensated for with higher savings in the EAF together with reduced consumption of slag formers.
