Which of the following statement is CORRECT for the extraction of Al from Bauxite :-

Options:

Answer:

Solution:

The Hall-Heroult process uses molten cryolite ( $N a_{3} A l F_{6}$ ) and fluorspar ( $C a F_{2}$ ) to dissolve alumina ( $A l_{2} O_{3}$ ). These additives lower the melting point of the electrolyte and significantly increase its electrical conductivity, making the electrolytic extraction of aluminum feasible and more energy-efficient.
