electrolytic precipitation of gold
Professional Gold CIL Plant Equipment Electrolytic Cell ...
Therefore, electrolytic method is adopted by most of the gold mines. Gold exists in the desorbed pregnant solution in the form of Au (CN) 2. Precipitation of gold, silver and little copper is done by the cathode in the electrolysis process, and so it is with hydrogen due to water deoxidization.

Gold Recovery, Cyanide, Electrowinning, details needed
Our company cleans equipment that is gold contaminated. The proposed plan is to build a holding tank that will contain ~50 gallons of technistrip, a cyanide based gold extraction solution. (Our system designs include exhaust, waste treatment, and life safety.) The parts will then be placed into the solution for the gold removal process.

precipitate on the bottom of the cells beneath the anodes as 'anodic slimes' or 'anodic sludge'. In the figure, the 'anodic sludges' are shaded, and some idea of the greater purity of the copper cathode as compared with that of the anode is shown by the smaller density of spots on the cathodes.

How is gold made? UCSB Science Line
The electrolytic method of gold refining was first developed by Dr. Emil Wohlwill of Norddeutsche Affinerie in Hamburg in 1874. Dr. Wohlwill's process is based on the solubility of gold, but the insolubility of silver, in an electrolyte solution of gold chloride (AuCl 3) in hydrochloric acid. The impure gold is cast into anodes of about 100 ounces each, which are suspended in porcelain cells, while the cathodes are .

Wohlwill electrolytic refining process for gold
I can help with electrolytic silver refining and chemical solution/precipitation refining methods for gold, silver, platinum and palladium. I think many refiners find that it is costprohibitive to refine gold electrolytically because there is so much inventory tied up in electrolyte.
