Froth flotation

Froth flotation is a process for selectively separating of 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. It has been described as "the single most important operation used for the

Froth Flotation Process Mineral Processing & Metallurgy

20/01/2021 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.

Model Predictive Control for Froth Flotation Plants

Froth flotation Froth flotation is a common method to extract a certain type of mineral from ore while depressing the amount of undesired minerals in the extracted concentrate. It is done by adding certain chemical reagents to selectively rendering the desired mineral hydrophobic. In a flotation cell, air bubbles then lifts the mineral. The resulting froth layer is then skimmed to produce the

Principles of Froth Flotation with Photos Minerallurgy

25/04/2021 Froth flotation utilises the differences in physico-chemical surface properties of the particles to be separated, especially differences in hydrophobicity. Bubbles rise through a heterogeneous solid-liquid suspension, accumulating certain of the solid particles, which attach by virtue of their hydrophobicity. The hydrophobic solid which attaches to the bubble is thus removed from the solid

OPTIMIZATION OF AIR-INJECTION SPARGERS FOR COLUMN

A mayor constraint on column flotation capacity is froth overloading. The carrying capacity of the froth depends on the bubble surface area available for bubble-particle attachment. The bubble surface area, and hence carrying capacity, can be increased by reducing the average size of bubbles for a given gas flow rate. Efficient and proper air sparging performance is vital to the success of
