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

Jan 01, 2015 Froth retention time, or the time particles and bubbles exist within the froth phase, consists of two time periods, i.e. the time for the froth to move vertically from the base of the froth phase to the level of the concentrate launder lip and the time for the froth to move horizontally to the edge of the flotation cell. However, froth
