The tailings cyanide agitators discharge to a washing thickener. The underflow is filtered and the filter cake repulped with barren solution and pumped to the residue dam. Filtrate is circulated back to the washing thickener. Overflow from the washing thickener passes to the low grade precipitation section and is treated similarly to the high grade solution. Barren solution is circulated back
