Froth Flotation an overview ScienceDirect Topics

The froth flotation process is commonly employed for the selective separation of a mineral species from a liquid–solid suspension of both valuable and unwanted gangue mineral particles. The valuable mineral species (which needs to be separated) is rendered hydrophobic by controlling its surface chemistry to provide the potential conditions for the attachment of the particles to air bubbles.

Flotation Froth an overview ScienceDirect Topics

The most widely accepted method for upgrading ultrafine coal is froth flotation. Froth flotation is a physicochemical process that separates particles based on differences in surface wettability. Flotation takes place by passing finely dispersed air bubbles through an aqueous suspension of particles (Fig. 17). A chemical reagent, called a frother, is normally added to promote the formation of small bubbles.

Jan 20, 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:

Dec 22, 2020 The principle behind froth flotation process is that sulphide ores are preferentially wetted by pine oil whereas gangue articles are wetted by water. In this process, the suspension of a powdered ore is made with water. Collectors like pine oil, fatty acids and xanthate are added to it.
