Provided are methods for dewatering a slurry from the leaching of a valuable ore with an aqueous solution of an effective leaching agent via a solids/liquid decantation system, providing an overflow depleted from solids and an underflow rich in solids that is washed counter-current through a number of solids/liquid decantation stages, the improvement implementing into the process line (a) a first Controller (CI) for monitoring and steering the leach product thickener; and (b) a second Controller (C2) for monitoring and steering the counter-current decanter. |
