Gold Flotation - Mineral Processing & Metallurgy
Finely divided metallic gold in milling ores floats readily, and a high-grade concentrate can be made by flotation if no interfering slime or gangue is present. Any good collector may be used for the flotation of gold, but organic collectors of the xanthate type produce a cleaner, higher grade concentrate than …
Sulphide Gold Ore Treatment by Leaching and Flotation Process
Flotation concentrates are dewatered and finely ground for maximum exposure of gold and sent to the cyanide plant. The grinding is preferably done in cyanide solution. Standard practice is followed as shown; the slight difference usually being more intense agitation as supplied by Super-Agitators with maximum aeration.

Processing technologies for gold-telluride ores. Generally, gold ores can be classified into two categories: the ‘free milling’ and ‘refractory’ ores. Free milling ores are those that require only conventional physical pre-treatment, such as grinding and sulfide flotation, to liberate the free gold and obtain a concentrate for further ...
Gold Concentrates | Crisson Gold Mine
Our Gold concentrates come from a open pit hard rock mine in the North Ga. Mountains. We dig quartz rock out of our pit, then run it trough our Stampmill to crush it into sand. That material is then run through our Trommels and then what is left in the sluice box is what makes our concentrates. We don’t take gold out or add Gold into the dirt!

Sulphide Flotation - an overview | ScienceDirect Topics
Grinding the ore with ceramic rather than iron balls was required to prevent cementation of gold chloride (Ferron et al., 2000). The concentrate tested was a flotation concentrate from the Northmet project, USA, assaying 14.7% Cu, 3.05% Ni, 0.14% Co, 26.7% S, 1.4 g/t Au, 2.2 g/t Pt, and 9.9 g/t Pd.
Sulfide Ores - an overview | ScienceDirect Topics
Froth flotation entails attaching fine Cu-sulfide mineral particles to bubbles and floating them out of a water–ore mixture. The flotation is made selective by using reagents, which make the Cu-sulfide minerals water-repellant (hydrophobic) while leaving the other minerals wetted (hydrophilic).
Rcovery of gold in pyritic ores - Mine Engineer.Com
Recovery of gold in sulfide ores has fallen into several categories. First is froth flotation, and second is cyanidation of the ores. Using cyanide to recover gold from sulfide ores generally results in 30 to 35% recovery, and the best I have heard of is around 50% recovery.
