refining gold with electrolysis

Electrolysis - Gold Refining Machine

Electrolysis is one of the methods used to recover metals with high purity. It is used in metal production from mining and recycling areas. Copper electrolysis, silver electrolysis and gold electrolysis are encountered most frequently in the industry. Unlike refining and leaching methods, it is possible to obtain metal with much higher purity.

Electrolytic Refining of Gold

2021-2-27 · The method just described aims at leaving gold in an insoluble state at the anode. Other impurities are usually left there, and the gold sponge, or slimes, needs further refining by methods, to be indicated later. By using a suitable electrolyte the gold can be dissolved from the anode bars and deposited in sheet form on the cathode, while many metals can be left in solution. The active agent ...
