fine separating flotation

Effects of fine–coarse particles interaction on flotation ...

The influence of fine particles on the flotation separation of minerals is becoming increasingly important as new fine grained deposits are exploited. Fine particles float poorly and less selectively under normal flotation conditions and have detrimental effects on the recovery of other minerals. Previous

Froth Flotation Process - Mineral Processing Metallurgy

Jan 20, 2021  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 formation of air bubbles.
