Froth Flotation Process

The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the …

Reagents types in flotation of iron oxide minerals: A review

ABSTRACT Recently, beneficiation of iron from low-grade ores with high impurities has been a matter of discussion. Flotation is one of the most effective technologies for the upgrading of low-grade, finely grained iron ores. This method can also be applied to reduce the impurities content in magnetite concentrates obtained using wet low- and high-intensity …

Selective flotation of iron oxide

Selective flotation of iron oxides from associated gangue minerals has proven difficult in the past with standard collectors, such as sulfonates and fatty acids. As a result, recent work has been di­ rected toward silica flotation with calcium activation …

Unveiling the enhancement mechanism of Fe ion for muscovite flotation

In the current study, the effect of iron ions dosage on muscovite-NaOL flotation recovery had been sequentially investigated in different pH.
