In order to overcome the difficulty of extracting gold from gold-bearing sulfide ore by cyanide process, flotation was adopted based on mineralogical analysis. Mineralogy shows that gold particles are of superfine structure and mainly enclosed by sulfide ores. Primary gold-bearing sulfide ore is fine-grained pyrite and arsenopyrite. The paper describes the effects of ratios …

The total share of xanthates used in US plants is ~60%, dithiophosphates – about 40%. Suppressors of gangue minerals are not usually used in flotation of copper disseminated ores. But if the pulp has an increased content of slimes, then liquid glass (up to 0.4 g/t) is added to the main copper flotation and to the copper concentrate re-cleaning.

Pre-19th century placer mining operations used mercury to dissolve the gold in crushed ore, making it easier to recover. Later innovations include the MacArthur-Forrest Process and borax flux extraction. However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules.
