Along with mechanized mining equipment, froth flotation dramatically improved the efficiency of gold mines. Thanks to this process, miners and refiners are able to extract quality minerals from ore at lower grades than has been previously possible – making it perhaps the most important mining industry innovation of the 20th century.

Gold flotation is widely used in the case of refractory ores, in which small-sized gold particles, locked within sulfide minerals, are recovered through flotation of gold-bearing minerals (Marsden and House, 2006). It is also an effective means for separating free gold from silicate particles present in ore.

A great deal of work has been reported on specific ores, but such studies rarely distinguish between the flotation of native gold and other gold minerals. Flotation of gold ores covers a broad field, and it is a rather difficult subject to generalize on. Most problems in gold ore flotation are not connected with floating metallic gold.
