please mark the answer as brainliest and follow me

Explanation:

Extracting aluminium from bauxite

Introduction

Aluminium is too high in the electrochemical series (reactivity series) to extract it from its ore using carbon reduction. The temperatures needed are too high to be economic.

Instead, it is extracted by electrolysis. The ore is first converted into pure aluminium oxide by the Bayer Process, and this is then electrolysed in solution in molten cryolite - another aluminium compound. The aluminium oxide has too high a melting point to electrolyse on its own.

hope this helps you....

Answer 2

Answer:

aluminum ore is called bauxite. The bauxite is purified to produce aluminum oxide, a white powder from which aluminum can be extracted.
