Answer:
The term that refers to the refining of aluminium by electrolysis is electrometallurgy.
Step-by-step explanation:
Electrometallurgy is a set of technologies, together with electricity and other factors, whereby physical and / or chemical reactions are obtained which is used to obtain and / or refine materials; thus being part of electrochemistry. Electrometallurgy is defined as the branch of metallurgy that uses electrical energy for the production and treatment of metals. The electrical energy is converted into heat in order to produce the necessary temperature for the process or to decompose a compound by electrolytic action in which the heat generated is relatively small or by electrolysis, in which the amount of heat used is necessarily big.
