bauxite wash plants. The procedure uses a centrifuge, operating at an rpm and duration designed to match the g-forces in the wash plant, to spin sample vials which are then separated by volume prior to analysis. The overflow and underflow of these vials were found to be very similar in size and consistency to that of known wash plants.
The result of the research shows that the higher alumina content of the raw bauxite, the longer washing time is needed moreover the higher quality of the washed bauxite is produced.

The Tayan bauxite resources are located on the hills between the swampy areas. The bauxite ore quality in this area varies with range of Al2O3 content is about 30 – 60 % and RSiO2 content is about 2 – 6 % of the washed bauxite (WBx) ore. The CGA plant needs WBx ore feeding as 851,000 tons/year @ 47.5% Al2O3 and 3.8% RSiO2.
Additionally, a crushing, screening, stockpiling, and loadout facility was established on the bank of the Demerara River. The loadout facility design was based on an expected total production of 5 million tonnes (Mt) of high-quality washed bauxite, to be processed at a rate of 330,000 t/a at total capacity, with an estimated 15-year production ...
