Serpeck's process is the process of converting bauxite into aluminum nitride. This process is generally used when silica is present in the bauxite ore. Therefore, Hall's process, Baeyer's process and Serpeck's process are the various processes used for the purification of bauxite. Hence, options A,B and C are correct. Separation ...

Note The process of refining bauxite to produce alumina is called the Bayer process. This process can be heavily affected by the presence of organic impurities. The Bayer process is considered uneconomic when bauxites have more than [10% ]silica, because sodium aluminium silicate is formed, reducing yield and in this case some other ...
