TECHNICAL NOTES 9 FLOTATION

9-5 The volume of pulp that is swept by a bubble per second is where Ub is the local rise 4 D2 bhUb velocity of the bubble and Dbh the bubble diameter projected on to the horizontal plane. This is generally different to the volume equivalent bubble diameter Dbe because a rising bubble distorts into an ellipsoidal shape unless it is very small.

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 …
