Separation of silica from bauxite via froth flotation ...
2009-3-1 Bittencourt, 1989, Bittencourt et al., 1990, aiming to obtain a gibbsite concentrate that could be used as raw material for the production of alumina refractories, tried direct flotation of the bauxite minerals from a Brazilian ore sample, composed basically of gibbsite (50%), kaolinite (15%) and quartz (35%). This flotation was carried out in two steps: the first step was the flotation of gibbsite/kaolinite

2021-1-15 By reverse flotation of the ore, a high-grade bauxite concentrate with A/S ratio 8.54 was obtained, however the Al 2 O 3 recovery remained low at 42.87%. Although the A/S rate achieved by the flotation was adequate for the Bayer process, Al 2 O 3 recovery was considered to be low for flotation process. It was deduced that the separation of reactive silica by flotation with plausible recovery was
