process of concentration of iron ore

Characterisation and magnetic concentration of an iron ore ...

· Based on the ore characteristics ( particle size, mineralogy and grade), gravity concentration (jig and Humphreys spiral), magnetic separation (low and highfield) and inverse ionic flotation (especially applied to pellet feeds) are used [3], [4]. It is estimated that for each tonne of beneficiated iron ore, 400 kg of tailings are produced.
