Flotation of Gold and Gold-Bearing Ores ScienceDirect

A great deal of work has been reported on specific ores, but such studies rarely distinguish between the flotation of native gold and other gold minerals. Flotation of gold ores covers a broad field, and it is a rather difficult subject to generalize on. Most problems in gold ore flotation are not connected with floating metallic gold.

Froth Flotation and Gold Extraction Manhattan Gold & Silver

Jul 23, 2014· 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).Онлайн-запрос

Improved recovery of a low-grade refractory gold ore using

In this work, different flotation–preoxidation–cyanidation methods are considered for treating a low-grade refractory gold ore. On the one hand, the results of selective flotation show that 22% and 31.1% of total Sb and As, respectively, remained in the final tailings and only about 28% of the total Au remained for further cyanidation processes.
