A gold cyanide leaching plant uses four CCD thickeners. Each is being fed with flocculant and a clear overflow obtained. Now, planning is to produce paste tailings out from the last thickener in the series. At least 68% solids by weight is needed. Problem is that the slurry is too flocculated and % solids cannot be higher than 62%. Cumulative flocculant addition amounts to up to 75 grs/ton. A solution has been proposed to add flocculant just to the last thickener in the CCD arrangement; however, the superintendent is against it. What can be done instead?
