Mining and Refining Process - World Alumini

The spent liquor is heated through a series of heat exchangers and subsequently cooled in a series of flash tanks. The condensate formed in the heaters is re-used in the process, for instance as boiler feed water or for washing bauxite residue. The remaining caustic soda is washed and recycled back into the digestion process. 7. Classification

Why don't power plants use salt water whe

Pretty much all modern plants used combined cycle generators where they already recover waste heat and use it to pre-heat the combustion products going into the turbine (or other generator). There isn't much recoverable waste heat left over, and adding additional equipment becomes very expensive and inefficient very quickly.
