Two types of Bauxite are mined in Weipa, Northern Queensland, and are designated as Andoom and Weipa ores depending on the deposit. To improve the grade of these ores washing is usually done which results in a lot of the constituent siliceous material being washed away. The resultant bauxite product then achieves a grade of about 60% …

The scrubber pulps the bauxite into a slurry which then passes over a trommel screen at the scrubber discharge. The screen separates the fine bauxite from the coarse intrusions and the trommel underflow is then pumped to the downstream process plant. The intrusions are rejected as trommel overflow and conveyed to a waste dump.
