Mining and Refining Process

The bauxite residue sinks to the bottom of the settling tanks, then is transferred to the washing tanks, where it undergoes a series of washing stages to recover the caustic soda (which is reused in the digestion process). Further separation of the pregnant liquor from the bauxite residue is performed utilising a series of security filters.

Mining and Refining Process

Bauxite is generally extracted by open cast mining, being almost always found near the surface, with processes that vary slightly depending on the location. Before mining can commence the land needs to be cleared of timber and vegetation.
