Ore washing is the process of by the use of water or mechanical force to agitate and scrub raw ore, wash and separate the clay from ore. The alluvial ore deposits ( like gold, platinum, tungsten, tin ) and other minerals such as lead, copper, iron and manganese which are deeply oxidized and weathered, usually need to be washed to remove some ...
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.
