Ore Characteristics The bauxite ore is very hard and massive in the top and moderately hard and spongy below. The pale buff to creamy white coloured bauxite is mostly of high grade and is recorded mostly on surface. Bauxite, pale pink in colour and with a clayey appearance, has been found to occur towards the lower part of the bauxite zone.
Bauxite is an ore which contains iron, titanium and gallium compounds in addition to aluminium silicates. The chemical bonds cannot be separated from each other by simple melting. Because the aluminium cannot be melted out, the unwanted substances are separated out chemically with caustic soda. The silicate is then burnt, forming aluminium oxide.
