One of the most common techniques for upgrading bauxite ores is froth flotation (direct or reverse) using various reagents [ 12, 13, 14 ], while magnetic/gravimetric separation, reductive roasting, or selective grinding followed by magnetic separation has also been used over the years [ 10, 15, 16, 17 ].
4.1.1 Bauxite Grinding and Slurry Storage Bauxite is ground to less than 1.5 mm particle size at the refinery, using semi-autogenous grinding mills (SAG and/or Ball mills) to ensure sufficient solid-liquid contact during the digestion phase, which improves alumina extraction efficiency. A …
Wet grinding of the bauxite ore in rod mills, ball mills, or semiautogenous grinding mills to produce fine slurry. Digestion of the slurry by caustic soda (NaOH) at strengths exceeding 170 g/L in vessels under pressure at temperatures ranging from 145 to 265°C depending on the type of bauxite being processed.
CYQUEST® BGA positively impacts the rheological property of bauxite slurry by reducing the viscosity and stickiness during the grinding process. As a result, less energy is required and the specific energy consumption per ton of bauxite ground is reduced. This less viscous slurry is also easier to pump and again requires less energy.

Wet grinding of the bauxite ore in rod mills, ball mills, or semiautogenous grinding mills to produce fine slurry. Digestion of the slurry by caustic soda (NaOH) at strengths exceeding 170 g/L in vessels under pressure at temperatures ranging from 145 to 265°C depending on the type of bauxite being processed.
Calcined Bauxite is obtained by calcining (heating) superior grade Bauxite at high temperature (from 850 °C to 1600 °C). This removes moisture thereby increasing the alumina content. Compared to an alumina content of about 57 % to 58 % in raw Bauxite, Calcined Bauxite has an alumina content of 84 % to 88 %.
This laboratory study investigates selective grinding and beneficiation options for a Greek bauxite ore.
