Extraction of aluminum can be understood by

The purpose of adding cryolite is :

A

to increase the electrical conductivity of pure aluminium

B

to higher the melting point of `Al_(2)O_(3)`

C

to remove the impurities as slag

D

to increase he AI % in the yield

Text Solution

Verified by Experts

The correct Answer is:
A
`Na_(3) AIF_(6)` lowers the m.pt. and increases the conductance of melt.
Hence, (A) is the correct answer.
