(2015). Roasting Followed by Magnetic Separation: A Process for Beneficiation of Titano-Magnetite Ore. Separation Science and Technology: Vol. 50, No. 8, pp. 1221-1229.

Most of iron ore resources are composed of metamorphosed banded iron formations (BIF) in which iron is commonly found in the form of oxides, hydroxides and to a lesser extent carbonates. The chemical composition of iron ores has an apparent wide range in chemical composition especially for Fe content and associated gangue minerals.

Re-beneficiation of iron ore tailings from the conventional beneficiation plants The hematite ore (Fe 2 O 3) is always associated with limonite & goethite ores, which cannot be attracted by high gauss magnetic separators in the conventional beneficiation plants. Such tailings have 30-50% left-over Fe, which is a waste of natural resources.
