Question

short note on :- Extraction of Aluminium ​

Answer 1

Answer:

Aluminium ore is called bauxite (Al 2O 3). The bauxite is purified to yield a white powder – aluminium oxide (also known as alumina) – from which aluminium can be extracted. The extraction is done by electrolysis , but first the aluminium oxide must be melted so that electricity can pass through it.
