These bauxite solids are then passed through a counter-current washing train (mud washers) using water to recover as much of the caustic as possible to enable it to be returned to the recycled caustic liquor circuit. The washed solids from the counter-current washing train are called process residue and are pumped to the RDA (refer to Section 4.2).
