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.mining and refining – process - world aluminiumunlike the base metal ores bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. ore quality can be improved by relatively simple and inexpensive processes for removing clay known as “beneficiation” which include washing wet screening and mechanical or manual sorting.
