The souted bed electrolytic reactor (SBER) concept is base don the use of spouted beds of metallized or metallic particles as cathodes for electrolytic revoery of metals from aqueous solutions. In the SBER, the treated liquid is introduced as a high velocity jet at the bottom of a conical vessel via a central draft tube. This liquid jet entrains particles which disengage from the liquid flow in a region above the particulate bed, and are then distributed onto the cathodic "feeder cone" at the bottom of the reactor which directs particles back toward the inlet of the draft tube for re-entrainment. The "pumping action" of the spout circulates the particles through the vessel in a toroidal fashion; upwards in the spout and downwards in the annular region. These systems have been demonstrated to provide superior performance in terms of high current efficiencies and current desnities, down to low metla concentrations, as well as providing for facile recovery of the metal in a high quality form for recycling.
