Vedclass · Answer

(C) Aluminum is a highly reactive metal and cannot be reduced by carbon because it has a high affinity for oxygen. Therefore,it is extracted from its ore (alumina,$Al_2O_3$) by the process of electrolytic reduction (Hall-$H$éroult process). In this process,molten $Al_2O_3$ mixed with cryolite $(Na_3AlF_6)$ and fluorspar $(CaF_2)$ is electrolyzed.
