4 Types of Gold Ore Froth Flotation Combined Process

For vein gold ore with high arsenic and sulfur or high carbon argillaceous, the gold sulfide concentrate can be obtained by the froth flotation, and then the flotation concentrate can be recovered by the thiourea leaching process. Thiourea gold extraction is a kind of increasingly sophisticated gold extraction method with low toxicity. Thiourea acid solution has the fast gold and silver ...

Froth Flotation and Gold Extraction - Manhattan Gold

23/07/2014  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. In gold mining, froth flotation is used to separate gold from gangue by utilizing gold’s ...
