the bauxite to provide a desired quality of product. A primary objective of the beneficiation process is to reduce the silica content in the ore, as the latter reacts with caustic soda during the digestion step to precipitate out as insoluble sodium aluminium silicates, e.g. 2Na2O.2Al20;,.3Si02.2 H20. This salt is

Bauxite Beneficiation: An Approach to Value Addition in ...

02.07.2021  Metallurgical bauxite is a low-value bulk ore, and therefore preference is often given to simple beneficiation techniques, such as crushing followed by dry screening or washing and scrubbing processes. The most effective way to remove both kaolinite and goethite is by washing, followed by attrition scrubbing and desliming through removal of clay-rich super fines in hydro-cyclone. Processing of bauxite for smelter grade alumina is quite sensitive to bauxite

In the Bayer plant, bauxite mineralogy affects process efficiency by driving the chemical reactions that occur in the process. If the Run Of Mine (ROM) bauxite is of lower quality, in some cases the beneficiation by means of physical separation process is economical feasible. These generally low-cost processes can extend the lifetimes of existing bauxite mines considerably, and substantially improve the technical and economic basis of the Bayer process

Abstract. Many bauxite reserves in India have Al 2 O 3 /SiO 2 ratio of 4 to 6 and hence pose difficulties in production of alumina through the Bayer process. The extraction of alumina from bauxite in low temperature digestion circuit frequently involves a desilication step in which kaolinite dissolves and reprecipitates as sodalite, a caustic insoluble sodium alumino silicate.
