Although thermodynamically feasible, in practice, magnesium metal is n – InterviewSolution

1.	Although thermodynamically feasible, in practice, magnesium metal is not used for the reduction of alumina in the metallurgy of aluminium. Why ?
Answer» SOLUTION :Below the temperature (1623 K), corresponding to the point of intersection of AL,O, and MGO curves inmagnesium can reduce alumina as discussed in above.Butamgnesiumisamuchcostlier metalthan ALUMINIUM and hence the processwill beuneconomical.
