Abstract
Portable apparatus is disclosed for recovering metal from metal bearing solutions. The apparatus includes a chamber arranged to be mounted on a container for the solution to establish a fluid flow path between an anode and cathode in the chamber for deposition of metal on the cathode, the unit being arranged to prevent unauthorized removal of deposited metal from the cathode.
Claims20
Apparatus for recovering metal from metal bearing solutions comprising:
- an electrolysis chamber open at the top and having side wall means and a bottom wall, means normally securing the top of said chamber against access to the interior thereof, means defining an aperture in said bottom wall and at least one opening in said side wall means, a first electrode positioned in said chamber adjacent said side wall means, means defining at least one opening in said first electrode, a second electrode of opposite polarity than that of said electrode and positioned at or near the center of said chamber, an impeller, means for driving said impeller to draw fluid into said chamber and to expel same from said chamber via said aperture and said openings, said opening in said first electrode being disposed so as to be out of register with said opening in said chamber wall means, and means for passing an electric current between said electrodes and through the solution in said electrolysis chamber to deposit metal from said solution onto one of said electrodes.
