Apparatus for the precipitation of metals from solution
Abstract
Abstract APPARATUS FOR PRECIPITATING METAL VALUES FROM SOLUTION ON MASSED DESCRETE PIECES OF SOLID PRECIPTANT. A PRECIPITATION VESSEL OF INVERTED CONICAL FORMATION IS CHARGED WITH THE PERCIPITANT, AND THE PREGNANT SOLUTION CONTAINING THE METAL VALUES IS INJECTED UNDER PRESSURE INTO THE MASS OF PRECIPITANT THROUGH A NOZZLE LOCATED AT THE DOWNWARDLY-DRIECTED APEX OF THE VESSEL. THE NOZZLE IS OF SPECIAL FORMATION COMPRISING AN OUTWARDLY DIVERGENT CHANNEL MEMBER OF CONICAL FORMATION INSET INTO A DISCHARGE ORIFICE TO PROVIDE AN ANNULAR NOZZLE OPENING CONCENTRICALLY SURROUNDING A CENTRAL NOZZLE OPENING. THE FORCE OF THE INCOMING SOLUTION CREATES A VOID IN THE MASS OF PRECIPITANT IMMEDIATELY ABOVE THE NOZZLE, AND, AS PIECES OF PARTIALLY CONSUMED PRECIPITANT FALL INTO THE VOID ABOVE THE NOZZLE, THEIR SURFACES ARE SCRUBBED CLEAN OF ADHERENT PRECIPITATE WHICH IS CARRIED UPWARDLY BY THE SOLUTION TO OVERFLOW THROUGH A SCREEN THAT EXTENDS PREFERABLY VERTICALLY UPWARDLY FROM THE OVERFLOW RIM OF THE VESSEL.
