The terms for this are electroplating, electrowinning, and electrorefining.
2.
Electrorefining of copper was first demonstrated experimentally by Maximilian, Duke of Leuchtenberg in 1883
3.
For example, it can be recovered in the anode slime during the electrorefining process.
4.
Commercially, electrolytic cells are used in electrorefining and electrowinning of several non-ferrous metals.
5.
The plant employed rectangular blast furnaces for tin production, with additional processes such as electrorefining employed to obtain purified by-products.
6.
It is based around the use of reusable cathode starter sheets for copper electrorefining and the automated stripping of the deposited cathode copper from them.
7.
During electrorefining of copper and nickel, noble metals such as silver, gold, and the platinum group metals precipitate as " anode mud ", the feedstock for the extraction.
8.
In the PYRO-B processing of such fuel, an electrorefining step is used to separate the residual transuranic elements from the fission products and recycle the transuranics to the reactor for fissioning.
9.
The process of electrorefining copper consists of placing a copper anode ( about 99.5 99.7 % pure copper At the applied electrical potential, copper ions migrate from the anode and deposit on the cathode, forming cathode copper.
10.
During electrorefining of copper and nickel, noble metals such as silver, gold and the platinum group metals as well as selenium and tellurium settle to the bottom of the cell as " anode mud ", which forms the starting point for their extraction.
