Froth flotation has been widely used in upgrading iron ores 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 used route in iron ore flotation This review is focused on the reverse flotation of iron oresJul 25, 2019 Flotation of iron ore can thereby be achieved either by floating the iron onto the froth, where it is concentrated, or leaving it in the liquid and floating off unwanted minerals Another common method of iron ore concentration, magnetic separation, uses magnets to shift and concentrate magnetic particles like ironIron ore: Confounding the expectations of experts EdisonIn the case of highiron marmatite ores, marmatite particles 23 Microflotation tests poorly respond to the flotation with copper sulfate as the activator, leading to a bad beneficiation (low concentrates The microflotation of the highiron marmatite particles grade and recovery)(PDF) Activation of highiron marmatite in froth flotation
