Purification of aluminium by electrolytic refining is carried out by :

Answer»

Hoope process
Hall process
Baeyer process
Serpeck process

Solution :Hoope's process is a metallurgical process used to obtain the aluminium metal of very high purity by electrolytic refining. In this process, alumunium ions from the FUSED mixture are discharged which at the cathode as pure metal rises to the surface while impurities remain at the BOTTOM. The aluminium metal OBTAINED by this process is `99.98%` pure.
