    Oct 17, 2019· The bauxite is loose and easily mined with front-end loaders. Beneficiation of the ore before it is shipped out of port involves simple screening and washing. Selective mining ensures that only the highest grades are mined. Below the pisolitic bauxite horizon is a nodular ironstone layer.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.
