Electrolytic processes for gold and other precious metals ...
2017-10-12 The electrolytic refining process for gold uses hydrochloric acid as the electrolyte. The anode is made of gold alloy and the cathode is usually a thin sheet of high purity gold. The electric current ionises the electrolyte and transfers dissolved gold from the anode to the cathode, thereby increasing the purity of the gold

Electrolytic Refining of Gold
2016-3-25 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.

Electrolytic Refining - Mining Fundamentals
2014-2-14 Gold - The electrolytic gold recovery process employs hydrochloric acid as an electrolyte, a thin sheet of gold with more than 99.5% purity as a cathode, and a gold alloy anode. Following the ion transfer, high purity gold is transferred onto the cathode. This process is known as the Wohlwill process.

Gold Plating - an overview ScienceDirect Topics
Gold was deposited by coating the article with a Au–Hg alloy and then heating it to remove the mercury. Currently, electrolytic gold plating is done using [Au(CN) 2] − or, to a lesser extent, [Au(SO 3) 3] 3−, usually as the potassium salt. Baths have been formulated using acidic, neutral, and basic solutions to which agents are added to ...
