The maximum annual output of alumina was 53000 tonnes one year later the tikhvin alumina plant began production anew with a capacity of 50000 ty using a wet sintering process for the processing of highsilicon bauxite the plants annual output eventually climbed to 190000 ty the principle flowsheet for the plant is shown in figure
The most widely used chemical process of refining bauxite into alumina the bayer process involves dissolving the al2o3 out of the bauxite rock with caustic soda naoh at elevated temperature and pressure the al2o3 fraction of the bauxite is dissolved into
Therefore intensive research work related to biotechnology should be undertaken in the future to develop comprehensive and efficient process for the bio beneficiation of the lowgrade bauxite
