Question

For each of the substance listed below, describe the role played in the extraction of aluminium.

Cryolite

Answer 1

1. Those minerals which contain a very high percentage of a particular metal from which metal can be profitably extracted is called ores.
2. Bauxite is the ore of Aluminum.
3. In the extraction process, Aluminum Cryolite is added.
4. Cryolite is a chemical compound with the formula $\mathit{N}{\mathit{a}}_{\mathbf{3}}\mathit{A}\mathit{l}{\mathit{F}}_{\mathbf{6}}$.
5. Cryolite is added to lower the melting point of Alumina since alumina is having a higher melting point.
6. So it is necessary to add Cryolite in the extraction process of Aluminum to reduce energy consumption and to make the reaction faster.
