17 - Flotation of Gold Ores

However, very little is known about the flotation properties of gold contained in various ores and the sulphides that carry gold. The sparse distribution of discrete gold minerals, as well as their exceedingly low concentrations in the ore, is one of the principal reasons for the lack of fundamental work on the flotation of gold-bearing ores.

Jul 13, 2016  GOLD FLOTATION. The flotation process, which is today so extensively used for the concentration of base-metal 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.

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).

1.3 Flotation and subsequent processes (refractory ore processing) The flotation process is described in detail in chapter 3.3. Native gold, gold tellurides, and sulphides that contain finely disseminated gold can be floated and recovered in a concentrate. In gold metallurgy flotation is often used as a pre-enrichment process for refractory ores.
