Metal extraction

Extraction of Aluminium
Aluminium is extracted from purified bauxite ore mainly Al2O3
The oxide is dissolved in molten cryolite which forms a solution which melts at around 1240K Al2O3 melts at 2435K therefore less energy is required
The solution is electrolysed so the main cost of the process is electricity which makes economic sense where cheap electricity is …
