Brief Introduction

Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water.

Froth flotation can selectively separate core minerals from middlings or tailings, making them high-grade mineral concentrate. Since froth flotation can separate minerals from already processed concentrates besides the primary ore, it is considered to have high efficiency in recovering minerals.

Working Principle

In the flotation machine, the slurry after the addition of the chemical treatment is stirred and aerated, so that some of the ore particles are selectively fixed on the bubbles and the surface of the slurry is scraped to form a foam product, with the other part left in the slurry, which achieves the purpose of separating minerals.
