Concentration of bauxite is done by different methods as there are different types of bauxite. Consider the process for concentration of bauxite. Process 1 : Employed for red bauxite to remove main impurity iron oxide. Process 2 : Employed for white bauxite to remove main impurity silica.
Highly reactive metals with lower reduction potentials than hydrogen are not obtained by electrolysis of aqueous solutions of their salts since their cations cannot be reduced at cathode in presence of water. Of the above metals, Magnesium is the only metal which has reduction potential less than that of Hydrogen. Hence, Option "B" is the correct answer.

The effectiveness of the oxiderich residue from bauxite refining (red mud) to remove inorganic Hg(II) from aqueous solutions was assessed. The aspects studied comprised the kinetics of the process (t = 1 min24 h), the effect of pH (), the interacting effect between salt concentration ( M NaNO3) and pH and the Hg(II) sorption isotherm.
Serpeck's process Bayer's method and Hall's method is used for the red bauxite which contains F e 2 O 3 and silicates as impurities. Serpeck's method is used for the white bauxite which containes silica as impurities.

Serpeck's process Bayer's method and Hall's method is used for the red bauxite which contains F e 2 O 3 and silicates as impurities. Serpeck's method is used for the white bauxite which containes silica as impurities.
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 ...
The metal obtained in the HallHéroult process is about 99% pure, and for most purposes it is taken as pure metal. However, further purification of aluminium can be carried out by the Hoopes process. This is an electrolytic process. Serpeck's Process Bauxite containing high percentage of silica can be purified by Serpeck's process.
