operation is a ccd circuit ofn thickeners in series where a slurry is fed to thickener i and a wash solution to thickener n; clear preg nant solution overflows thickener i and washed tails exit as under flow from thickener n. ccd circuits of this type are typically employed when the solids tend to slime heavily and where a filter is not

the leach slurry is transferred to a post-leach thickener (plt) followed by a countercurrent decantation (ccd) circuit consisting of five thickeners placed in series. wash water was added to the plt in a ratio of 1.5 t of water to 1 t of solids in the feed to the ccd circuit.
