A review of reagents applied to rare-earth mineral flotation
Silica gel. Silica gel has been shown to be a good depressant for gangue minerals barite, fluorite and calcite in the flotation of a Chinese rare earth deposit [ 128 ]. The depressing action was explained as an active siliceous colloid which selectively adsorbs to gangue minerals rendering them hydrophilic [ 128 ].Web
