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 kinetics of a pyritic gold ore ScienceDirect

Jan 17, 2011 Research Highlights Flotation kinetics of a pyritic gold ore was studied with respect to particle size. Gold recovery increased by 4% with grinding from a P 80 of 205 microns to 53 microns. Second order kinetics is a much better representation of semi-batch flotation. The first order flotation rate constant is independent of particle size in this range. The second order flotation rate constant

Froth Flotation and Gold Extraction Manhattan Gold & Silver

Jul 23, 2014 Most methods of water-based gold extraction are dependent on gold’s lack of buoyancy to work. However, froth flotation uses a different property of gold to separate it from ore. Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water).
