Most methods of waterbased gold extraction are dependent on golds 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).

Characteristics of native gold flotation Native gold is a mineral that is easy to float,the crystal structure of native gold is metallic lattice,forming the character of the metal bond. Because of the weak metal bonding force, the native gold has the characteristics of small surface wettability and easy to float.
Flotation is a method that is widely used in gold ore processing plant to process the rock gold ,commonly used in dealing with highly floatable sulfide minerals containing gold ore. Flotation process can maximum enrich gold to the sulfide mineral , tailings can be abandoned directly , the cost of processing plant is low, 80% of China's rock
2020518&ensp·&enspGOLD FLOTATION. The flotation process, which is today so extensively used for the concentration of basemetal sulphide ores and is finding increased use in many other fields. In 1932 flotation plants began to be installed for the treatment of gold and silver ores as a substitute for or in conjunction with cyanidation.
202054&ensp·&enspAPPLICATION OF FLOTATION TO GOLD ORE. A flotation plant is being erected at the Falcon mine, Rhodesia, to treat ore containing gold and copper. With the exception of the Mt. Morgan, the Etheridge, and the Great Fitzroy mines, Queensland, I have not heard of the flotation process being used successfully to treat ore containing an appreciable amount of gold.
