General principles of extraction of metals
This is applied for extraction of aluminium from bauxite (Al2O3.2H2O). Bauxite is contaminated with iron (III) oxide (Fe2O3 ), titanium (IV) oxide TiO2 )and silica (SiO2 ) . These impurities are removed by digesting the powdered ore with aqueous solution of sodium hydroxide at 420 K under pressure. Aluminium oxide dissolves in sodium hydroxide,
