The process is known as firerefining. The still impure copper is then cast into anodes for electrorefining. (ii) The leaching process ... such as gold, silver, platinum and tin, are insoluble in the electrolyte solution and so do not deposit on the cathodes. Instead, they are deposited as 'anode slime' on the bottom of the tank, which is ...
The principle usually followed in the electrolytic refining of metals is to cast the ... or electrolysed with insoluble anodes to recover the copper. As the operation proceeded, it was found that the ... after acidification the resulting silverfree copper solution is returned to the cathode cell for the deposition of the copper.

Electrowinning Wikipedia. Electrowinning, also called electroextraction, is the electrodeposition of metals from their ores In electrowinning, a current is passed from an inert anode through a liquid leach solution Apparatus for electrolytic refining of copper electrolytic cell, where they form a substance referred to as anode sludge or anode slime.
