Froth Flotation and Gold Extraction - Manhattan Gold

2014-7-23  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).

Nine Gold Extraction Processes for Vein Type Gold

2020-4-2  This gold extraction process is focused on the froth flotation process, which is suitable for mines with close co-existence between gold and sulfide and can only be recovered by smelting. It is also suitable for gold-bearing quartz vein mines with uneven coarse intercalation, which can obtain a higher gold recovery rate than the single froth flotation process.
