Froth Flotation Process - 911 Metallurgist

Mar 25, 2017 ... 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...

Froth Flotation - Department of Chemical Engineering

1 Froth Flotation – Fundamental Principles. Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and.
