Abstract: An electro-refining system in which the deposited metal is harvested without the need to remove the cathode from the slurry bath. The cathode has a hollow cavity permitting steam or hot water to be introduced to heat the cathode. During the deposition process, the heating of the cathode encourages the deposition process. When the deposited material is to be harvested, the cathode is heated to “melt” the bonds between the cathode and the deposited metal. Using a bracket which was installed before the deposition process and into which the deposited metal has been formed, the now-released sheet of deposited metal is easily removed.
