Hall-Heroult method

Vedclass · Answer

(B) The extraction of aluminium from pure alumina $(Al_2O_3)$ is carried out by the electrolytic reduction process known as the Hall-Heroult process.In this process,pure alumina is dissolved in molten cryolite $(Na_3AlF_6)$,which lowers the melting point of the mixture and increases its electrical conductivity.Electrolysis is then performed in a steel tank lined with carbon,where aluminium is deposited at the cathode.
