Feb 29, 2016 Flotation. Flotation is one of the most important gold recovery processes and its main restriction is to recover coarse gold particles ranging from 400 to 250 µm. This process recovers fine particles of free gold, gold associated in any form with sulphides, and native gold present in polymetallic deposits with certain degree of oxidation.

Feb 17, 2019 Froth flotation of gold is a widely used beneficiation method for treating rock gold ore in gold concentrating plant, which is often used to treat gold ore containing sulfide minerals with high floatability. The froth flotation process can concentrate the gold in sulfide minerals to the maximum extent, and the tailings can be directly discarded.

causes problems during the flotation of the PGM minerals due to the fact that talc consumes high amount of reagents. Therefore the purpose of the second part of this thesis was to investigate the possibility of removing talc prior to the flotation process by de-sliming. Two cyclones (36.9 mm and 76.0 mm) were used for de-sliming the flotation feed.
