Abstract: A zinc precipitation circuit is disclosed. The circuit comprises a vessel configured to carry clarified pregnant solution comprising a dissolved precious metal, the vessel further comprising means for delivering zinc particles; a precipitate filter downstream of the vessel configured for solid-liquid separation; at least one classifier downstream of the vessel and upstream of the precipitate filter and further being configured to separate the zinc particles from other precipitates from the clarified pregnant solution; and, a recycle feed stream configured to deliver the zinc particles separated from other precipitates to the vessel. A method of recovering a precious metal via a zinc precipitation is also disclosed. The method comprises the steps of: providing zinc particles to a clarified pregnant solution; forming a precipitate by precipitating said precious metal from the clarified pregnant solution by virtue of the zinc particle addition; separating the zinc particles from other portions of the precipitate, thereby forming a concentrate of the precious metal; recycling the zinc particles separated out by using them for providing to the clarified pregnant solution; and, smelting the concentrate to recover the precious metal.

Abstract: A system [100'] and process [100] for the continuous recovery of metals is disclosed. The system [100'] comprises a continuous acid wash system [10'], a holding tank [60], a continuous elution system [20'], a continuous electrowinning system [40'], a carbon regeneration system [30'], and a continuous carbon loading/adsorption system [70']. The systems and methods disclosed overcome the disadvantages associated with current systems and processes which utilize batch process steps and equipment designed for batch processes. The systems [10', 20', 30'] are each configured to receive a continuous inflow of a solution or slurry and deliver a continuous outflow of a solution or slurry, without interruptions which are common with conventional metal recovery systems [9000'].
