(i)The method used for refining nickel is called
Mond's process.
(ii) Aluminium is extracted from bauxite ore which is first converted into alumina.
Aluminium is extracted by electric reduction of alumima for which alumina needs to be melted.
The melting point of alumina is over 2000°C.
To reduce the melting point of alumina, Cryolite is used as catalyst to reduce its melting point.
