Gold Flotation - Mineral Processing & Metallurgy

Finely divided metallic gold in milling ores floats readily, and a high-grade concentrate can be made by flotation if no interfering slime or gangue is present. Any good collector may be used for the flotation of gold, but organic collectors of the xanthate type produce a cleaner, higher grade concentrate than coal tar-cresote oils.

Recovering Gold through the Froth Flotation Process

Froth flotation works by exploiting the hydrophobic properties of gold molecules. First, ore is ground into an extremely fine powder. The powdered ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold's hydrophobicity. This mixture is placed into a large tank filled with distilled water.

Flotation Froth - an overview | ScienceDirect Topics

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.
