How is Bauxite purified by Serpeck's process? Video Explanation Answer Finely powdered bauxite (Al2 O3 )is heated with coke and N2 to 2000 K. Alumina forms aluminium nitride and silica is reduced to Si which is volatile. The hydrolysis of aluminium nitride gives aluminium hydroxide which on heating gives pure alumina.

Hint: We know that Serpeck's process is used for purification of Bauxite. Bauxite contains impurities of silica in excess amount, which needs to be removed. The bauxite powder is mixed with carbon and heated under high temperature (above 1800^circ C) and a current of nitrogen is passed. Through this process aluminium nitride is obtained ...
