The schematic diagram of the lime sinter process is illustrated in Fig. 2. The major steps involved are described as follows: Get Pricethe process of extracting alumina from bauite,Alumina refining produces alumina (Al2O3) from the bauxite ore, by exploiting the reversible reaction of the Bayer process1–3: The reaction is firstly driven in the sodium aluminate (NaAlO2) direction by the addition of caustic soda (NaOH) to bauxite. Bauxite residues are then removed, leaving the process liquid, termed “green liquor.”Bayer process - Wikipedia,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 (Al2O3), 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 aluminium metal.
