In the extraction of aluminium from alumina, liquid ...

Aluminium oxide has a very high melting point (over 2 0 0 0 o C) so it would be expensive to melt it. So it is dissolved in molten cryolite -which has a lower melting point than aluminium oxide. The use of cryolite reduces some of the energy costs involved in extracting aluminium.

Aluminium recycling - Wikipedia

Aluminium recycling is the process by which scrap aluminium can be reused in products after its initial production. The process involves simply re-melting the metal, which is far less expensive and energy-intensive than creating new aluminium through the electrolysis of aluminium oxide (Al 2 O 3), which must first be mined from bauxite ore and then refined using the Bayer process.

Why is cryolite used in Aluminium extraction?

Feb 14, 2020· Why is cryolite used in Aluminium extraction? Instead, it is dissolved in molten cryolite – an aluminium compound with a lower melting point than aluminium oxide. The use of molten cryolite as a solvent reduces some of the energy costs involved in extracting aluminium by allowing the ions in aluminium oxide to move freely at a lower temperature.
