Characterisation and magnetic concentration of an iron ore

Based on the ore characteristics (e g particle size mineralogy and grade) gravity concentration (jig and Humphreys spiral) magnetic separation (low and high-field) and inverse cationic flotation (especially applied to pellet feeds) are used It is estimated that for each tonne of beneficiated iron ore 400 kg of tailings are produced Get price
