Froth flotation is a process of using bubbles to separate minerals based on their relative affinity for water. Bubbles are induced in the slurry through aeration.

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.

A practical approach to plant-scale flotation optimization - SciELO

The effect of froth depth on concentrate grade for three air rates is shown in Figure 8. It can be seen from Figure 8 that as the air rate is increased, the concentrate grades achieved decrease. At a froth depth of more than 250 mm, the grades achieved for the J g 0.43, 0.60, and 0.88 cm/s were 1, 0.9, and 0.75 g/t respectively. In addition ...

Froth Flotation Process - 911 Metallurgist

2021年1月20日  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
