Refractory Gold | SGS

The other parameter that SGS experts consider when designing refractory gold treatments is whether or not to preconcentrate the gold-bearing ore. This is usually done by flotation of arsenopyrite, pyrite, or other gold-bearing sulfides. To be economically justifiable, preconcentration should meet two objectives.

Froth Flotation and Gold Extraction - Manhattan Gold & Silver

Froth Flotation and Gold Extraction. Most methods of water-based 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).
