Froth Flotation and Gold Extraction

Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water). Since its discovery, froth flotation has been a major component for the processing of sulfide-rich ores, including copper, coal, and refractory gold.
