The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef, the most important ore of aluminium, contains only 3060% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide. The aluminium oxide must be further purified before it can be refined ...

Solution Verified by Toppr Finely powdered bauxite (Al 2O 3) is heated with coke and N 2 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. Al 2O 3⋅2H 2O+N 2+3C 2000K 2AlN+3CO↑+2H 2O SiO 2+2C→Si↑+2CO↑

Nitric oxide does not form as a byproduct in Serpek's process. Hence, the option (D) is incorrect. Note: We have to know that the Serpek's process is mainly used for the purification of bauxite which contains high amounts of aluminium and silica as impurity. And it is a reaction of bauxite with cock and there is a formation of aluminium ...

The leaching of aluminium oxide from bauxite is called Baeyer's process. The process was invented by an Austrian Karl Joseph Bayer in 1888 In the Bayer process when bauxite was mixed with caustic soda, the alumina content in the bauxite would dissolve and separate itself from the other components, such as iron and silica, which would ...

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 ...

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 ...
