2019-2-26 Bauxite (red) contains Fe 2 O 3. and SiO 2 as the main impurities. It is crushed to a powder and is treated with a cone, solution of NaOH at 150-200°C (under pressure) when Al 2 O 3 dissolves.. The solution is filtered to remove Fe 2 O 3 and siO 2.The solution on hydrolysis at 50 -60°C give insoluble aluminium hydroxide.
