Pyrochlore flotation from silicate gangue minerals: Amine

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

Entrainment of Gangue Minerals in Froth Flotation

2020-8-31  When the hydrophobic minerals are the gangue minerals, the process is called “reverse flotation”; otherwise, it is simply called flotation. For simplicity of discussion, in the following, it is assumed that the gangue minerals are hydrophilic unless stated otherwise.
