Why extraction of aluminium is difficult ?

Answer»

Extraction of aluminium is difficult because :

(i) Pure aluminium oxide melts at 2050°C only. So, a large amount of energy is needed to maintain this high temperature.

(ii) A good amount of the aluminium vaporises at this temperature.

(iii) Fused alumina does not conduct electricity well.
