Recovering Gold through the Froth Flotation Process ...

Feb 06, 2018  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 of Gold and Gold-Bearing Ores - ScienceDirect

Jan 01, 2016  Most problems in gold ore flotation are not connected with floating metallic gold. The flotation recovery of free gold (throughout the text free gold is synonymous with liberated gold) is largely affected by physical constraints such as the shape and size of the gold particles and the stability of the froth.

Froth Flotation and Gold Extraction - Manhattan Gold Silver

Jul 23, 2014  Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water). Since its discovery, froth flotation has been a major component for the processing of sulfide-rich ores, including copper, coal, and refractory gold. In gold mining, froth flotation is used ...

The effect of copper activation on the behaviour of free ...

May 01, 2000  The slope of the free gold line increases slightly because there is less room on the bubbles for its attachment since there is a greater true flotation of the sulphides. The true flotation of the free gold increases from 37% to 42%. This phenomenon can be explained by the action of the water being transported from the pulp phase to the froth.

Optimisation of gold recovery by selective gold flotation ...

Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore, even when a proportion of the gold is free. Gold does float readily, however, and the free gold can be selectively floated away from an ore containing sulphides. This may be an alternative ...
