The bauxite residue is thickened to a high-density slurry using an advanced thickener, flocculation, and dewatering filtration technologies. The thickened red mud slurry is pumped via pipeline to the storage area and spread in layers, allowing it to de-water through a combination of drainage and evaporative drying.

bauxite ore is removed to a crusher following which the crushed ore is screened and stockpiled ready for delivery to an alumina plant. In some cases, ore is upgraded by beneficiation (washing, size classification, liquid/solid separation) to remove unwanted materials such as clay and silica. At the alumina plant the bauxite ore is
2.2.1. Washing system. We designed a washing system, including a washing tower and a storage tower, as shown in Fig. 1 (left panel). Bauxite residue and water entered the washing tower from the bottom at a ratio of 1:7, as determined in a preliminary experiment (shown in Figure B and C in the Supplementary Materials), because a considerable washing efficiency was observed, and the …

Adopting the process of washing bauxite in the beneficiation plant can reduce caustic soda consumption and equipment and piping scale in the alumina refinery (OPEX), and consequently the payback for the beneficiation plant can be less than 3 (three) years. Besides the caustic consumption reduction, the beneficiation plant decreases the refinery ...
crude bauxite ore is necessary to be upgraded in order to remove such reactive silica, iron and other impurities (Saba, 2011). Most bauxite mining companies in Indonesia have been already imple-menting methods of washing by wet screening in trommel screen and vibrating screen after crushing the ore. Yield of the washed bauxite is between 40-50%.

bauxite slurry caustic soda • Red mud, named after its color, is the main by-product of making alumina by the Bayer process • The red mud is separated from the pregnant liquor (sodium aluminate remains in solution) via sedimentation in a clarifier • The amount of red mud (as dry matter) varies from 0.4 ton to 2 ton per ton of alumina product,
The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer.Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide. The aluminium oxide must be purified before it can be refined to ...
