Update: in this process,what would be the metal on the Cathode and, what would be the metal on the Anode? what would be the solution consist of?What we must add on the solution as a catalyst? Should we use Potasium Cynide in the solution?
World''s most popular finishing site / Internet''s friendliest corner topic 3899 Electrolytic Refining Process of Gold . Q. Dear Sir, I would like to know how to recover Gold from Silver Sludge which comes out from the Wohlwill Cells (Electrolysis).
Fill hydrogen peroxide H 2 O 2 40ml per 2000 ml melted gold chemical water. stir it together and wait for 5 minutes. You have to fill hydrogen peroxide H 2 O 2 in melted gold chemical water to destroy cyanide chemical structure. So, it is not fully element. It cannot melt gold. If we do not fill hydrogen peroxide H 2 O 2 That makes the next step gold piece melted and change into .

SELECTIVE ELECTROWINNING OF SILVER AND GOLD FROM CYANIDE PROCESS SOLUTIONS By F. H. Nehl,1 J. E. Murphy,2 G. B. Atkinson,3 and L. A. Walters2 ABSTRACT The Bureau of Mines investigated the selective electrowinning of Ag and Au from cyanide solu tions contaminated with Cu with the goal of decreasing the amount of Cu codeposited.
Gold Electroplating is a method of depositing a thin layer of gold onto the surface of another metal. Gold plating finds its uses in jewelry, semiconductor industry. It often employed in electronics to provide a corrosion resistant surface. In this instructable, I am making alkaline gold plating solution which can deposit gold by electrolysis.
During electrolysis, the gold in the raw rock material is not dissolved and collects as a sludge under the anode. Together with gold other precious metals ( Silver, copper, lead, tin) concentrate in this anodesludge and can be easily skimmed off. Then using a suitable process the individual precious metals can be separated from each other.

Electrolysis, or electrolytic refining, is a technique used for extraction, as well as purification, of metals obtained by any refining method. In the electrorefining process, a block of impure metal becomes the anode, and a thin sheet of metal becomes the cathode. Both the cathode and anode are ...
Gold electrolysis was invented by Emil Wholwill in 1874. But various versions of this process have been developed over the years. It is an electrochemical process which has been applied in many largescale goldrefining establishments or industries. The principle of gold electrolysis is very straightforward or simple: Dore bar, which is a cast ...
In gold electrowinning process,when the electrolysis equipment is added with anions which are more easily absorbed by activated carbons, Au（CN）2ˉ is replaced by anion and the gold desorption is achieved. After the carbons loaded with gold are desorbed, pregnant solution is process via ionization. At last, solid gold is attained.
The silver chloride is then reduced to metallic silver and is then refined by electrolysis. If there is demand in the market for a higher purity gold, then the % pure gold from the chlorine refining process is cast into anodes to be used in the electrolytic refining process, also known as the Wohlwill process.

Electrowinning is the oldest industrial electrolytic process. The English chemist Humphry Davy obtained sodium metal in elemental form for the first time in 1807 by the electrolysis of molten sodium hydroxide.. Electrorefining of copper was first demonstrated experimentally by Maximilian, Duke of Leuchtenberg in 1883.
Electrowinning and smelting are the final stages of gold production. The concentrated gold solutions produced in the elution circuit (pregnant eluate and by the Sunrise Reactor, are passed through the electrowinning cells which converts the gold ions (charged gold particles) in the solution into solid gold.
