The design, construction and operation of these storage dams follow guidelines as set out in individual countries and undergo regular maintenance checks. Seawater Discharge. In some countries an early method of bauxite residue disposal was to transfer the material via pipeline to deep sea locations following treatment to reduce caustic soda levels.
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 .
The bauxite residue sinks to the bottom of the settling tanks, then is transferred to the washing tanks, where it undergoes a series of washing stages to recover the caustic soda (which is reused in the digestion process). Further separation of the pregnant liquor from the bauxite residue is performed utilising a series of security filters.
wash water is used, cooled, and reused accounts in large measure for the variation in wa er requirements. Although the supply of water for all plants but one was reported by the management to be ample for all plant needs, the economic factor of the cost of water differs considerably among plants.
