A Rotary Drum Scrubber (diameter 80 cm, length 200 cm, screen opening 2 mm) was applied to upgrade the crude bauxite ores. The research was started by crushing followed by scrubbing and screening. The scrubber is supported by water sprayer to achieve washed bauxite (+2mm of particle sizes) separated from tailing (-2mm of particle size).

Bauxite ore of 1 – 20 mm.grain size is crushed to fineness of 500µ grain size (Fig.3) Fig.3, Bauxite concentrate gave in preparation workshop
mina content increased from 48% Al 2O3 in crude bauxite to 55% Al2O3 in washed bauxite. On the other hand, reactive silica content decreased from 10% SiO2 to 3% SiO2. To continue this research, it is necessary to conduct crude bauxite washing process with RDS (Rotary Drum Scrubber) which could be operated continuously instead of batch method.
