What is the process of the extraction of aluminum? Quora
The aluminum oxide is introduced into the electrolytic cell which is usually based on the Hall–Héroult process . The aluminum oxide dissolves at high temperature into the molten Cryolite where it is electrolytically reduced to aluminum metal and oxygen.
