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.

The specific example of goethite that contains Al is of major significance for the beneficiation of bauxite during the production of alumina or refractories. Goethite-rich iron ore is yet another key application to be targeted with the restraints technique, as this ore could include large amounts of Al.

The efficiency of any iron ore value-adding operation is closely associated with detailed knowledge of the mineralogy, especially in the processing of lower grade and complex ores. There are a number of physico-chemical properties of iron oxide mineral phases (eg goethite, hematite and magnetite) that can be prudently exploited to enhance their processing efficiency.
