1 Froth Flotation – Fundamental Principles

2009-8-27  1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and

Flotation Froth - an overview ScienceDirect Topics

The use of froth in flotation is twofold. First, froth is used to convey the mineral-laden bubbles from the froth–pulp interface to the concentrate launder. Second, froth is used to remove entrained hydrophilic particles by the gravity drainage of water back to the pulp (Figure 13). The froth cleaning process can be improved by spraying (wash ...

What is Froth Flotation? - wiseGEEK

2021-1-25  Froth flotation is a process using air bubbles to separate materials based on their relative affinity to water. Bubbles carry reagent and hydrophobic materials to the top of a tank where they can be removed. Froth flotation has been used for more than a century in mining operations to separate valuable materials from excavated ores.

Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents. The selective separation of the minerals makes processing complex (that is, mixed) ores economically feasible.

Firstly, the froth in the flotation product was pre-separated from the slurry before conducting any treatment. By doing so, the coal slurry which did not contain stable froths would not need to be treated, which reduced the chemical and energy consumption. Secondly, the separated froth was deaerated using physical methods.
