  • How to Refine Gold: 2 Major Techniques of Gold

    2 天前  Gold electrolysis. Gold electrolysis is the second, good method used in gold-making industries to separate gold from the other metals. This procedure has been noted to produce gold that is almost 99.999% pure. The principle and equipment for gold electrolysis. Gold electrolysis was invented by Emil Wholwill in 1874.

    2020-6-25  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 ...
