  • CHAPTER9 FROTH FLOTATION AND ITS APPLICATION TO

    FLOTATION OF IRON ORES AND INDUSTRIAL PRACTICES Flotation has been used for concentration of low grade ores containing siliceous gangue, which appears to be the most abundant type in the world and the reserves of which, when based on a minimum tenor of 30 to 35 % iron, amounts to a respectable quantity of milliards of tons30/07/2020· Iron ore flotation can be performed in two technical routes: direct flotation of iron oxides and reverse flotation of gangue minerals with depression of iron oxides Nowadays, reverse flotation is the most commonly usedFlotation of Iron Ore: A Brief Review MDPIWhen the concentration of the ore is complete, it is time for pelletisation Concentration means the beneficiation of finely ground ore by separation into a concentrate of iron ore powder with a very high level of purity Flotation is a chemical process for particle separationConcentration LKAB
