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).

Gold Flotation Mining Solution Mineral Processing

The recovery of gold from gold-bearing ores depends largely on the nature of the deposit. Other common occurrences of gold are alloys with copper, tellurium, antimony, selenium, platinum group metals and silver.
