Pyrite is removed from coal by a 2-stage froth flotation. In the 1st stage, coarse pyrite is removed as underflow in a conventional froth flotation operation. In the 2nd stage, the froth product from the 1st stage is subjected to froth flotation by using a coal flotation depressant and a pyrite ...

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

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 …
