Question

can you please help explain the extraction of aluminium

Answer 1

Answer:

Aluminium ore is called bauxite . The bauxite is purified to produce aluminium oxide, a white powder from which aluminium can be extracted. The extraction is done by electrolysis. The ions in the aluminium oxide must be free to move so that electricity can pass through it.

please make me as brainliest ....

In the metallurgy of aluminium, the metal is to be isolated from alumina (Al2O3) by carrying out its electrolytic reduction. It is therefore, mixed with cryolite (Na3AIF6) which lowers its melting point to 1173 K. Moreover, cryolite also increase the electrical conductivity of alumina.
