Fine Particle Processing Of Iron Ore Slimes From Wash Plant

The efficiency of reduction-roasting/magnetic separation of hematite, goethite and any extremely finegrained iron ore, which is non-responsive to conventional processing techniques, is reviewed. Roasting equipment, roasting mechanism, superior results over conventional techniques, and certain advantages are highlighted.Dry processing of iron ore presents an opportunity to eliminate costs and wet tailings generation associated with flotation and wet magnetic separation circuits. STET has evaluated several iron ore tailings and run of mine ore samples at bench scale (pre-feasibility scale). Significant movement of iron and silicates was observed, with examples ...processing of iron ore slimes by state of art vertical pulsating wet high intensity high gradient magnetic separation. The wash plant tails assayed 46.45%Fe, 18.03%SiO 2, 5.25% Al 2 O 3, and 6.10%LOI. The process comprises of high pressure cycloning of dispersed pulp to remove slimes less than 10 microns.
