Question

Is the production of Aluminium metal by reduction of Alumina (Al2O3) a
viable process? What are the disadvantages?

Answer 1

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 «f the aluminium vaporises at this temperature.
