With this flow configuration a large portion, approximately 70%, of the gold and silver dissolved in the grinding circuit will flow via the thickener overflow directly to the precipitation circuit. The four 8.0 meter diameter x 8.5 meter high leach tanks are sized for a total retention time of 48 hours at 45% solids.
