Common Questions About Froth Flotation Process Technology
The froth flotation process mainly includes grinding, slurry adding, froth flotation separation and dehydration of products and tailing products after froth flotation. Before the flotation operation, the ore needs to be ground to an optional size range by the grinding mill, generally less than 0.1 mm.

Froth Flotation Process - Mineral Processing & Metallurgy
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.
