Entrainment of Gangue Minerals in Froth Flotation ...

2020-8-31  Small-scale flotation tests with granular and flaky minerals indicated that the entrainment of hydrophilic gangue was controlled by four factors, particle mass and shape, water recovery, and slurry viscosity, of which viscosity was a variable that was to be taken into account especially in the flotation of very fine minerals .

Pyrochlore flotation from silicate gangue minerals: Amine ...

2021-9-1  Silicate minerals are the main gangue constituents during pyrochlore flotation, as the majority of iron oxide, sulphide, and carbonate minerals are removed upstream. However, pyrochlore has similar surface properties to quartz and other silicate minerals, making its selective separation challenging ( Gibson et al., 2015a ).

Mechanism for the recovery of silicate gangue minerals in ...

2007-7-1  1.. IntroductionFlotation is a complex process in which valuable minerals are separated from gangue minerals ().The separation is based on the surface properties of each mineral phase present in the suspension (Mitchell et al., 2005, Çilek and Yilmazer, 2003, Luz et al., 2002).Flotation performance is dependent on several key factors, such as particle size and surface chemistry.
