Sagot :
The correct option for the process used to refine aluminum from its bauxite ore is option D.
D. Smelting
The reason why smelting is the correct choice is as follows;
Bauxite is the aluminum ore from which alumina, also known as aluminum
oxide, Al₂O₃, is produced. Bauxite is extracted from the topsoil regions of
some subtropical and tropical regions, and the Bayer process is primarily
then used to produce alumina from the bauxite.
Aluminum is produced from the alumina by an aluminum smelting process
known as the Hall—Heroult electrolytic process which involves the use of a
carbon anode and direct current to produce aluminum by reducing the
aluminum oxide
