Wohlwill Electrolytic Process An old and wellestablished process, the Wohlwill method is widely used in major gold refineries, often in conjunction with the Miller process. (For typical jeweler''s scraps and wastes, a preliminary refining step, such as the Miller or inquartation process, is required.)

12/10/2017#0183;#32;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 at the cathode. This refining process is known as the Wohlwill process. Silver and other precious metals can be refined using the same electrorefining technique.
6/3/2008#0183;#32;The most you can get for gold is % that is for single refining and only if you spend a long time putting a lot of nitric acid, usually it''s between to %. You can achieve % through electrolytic refining sometime called electrorefining.
This process is known as the Wohlwill process. The Miller chlorination process is an economical refining process that separates gold of about % purity, which can then be electrorefined to improve purity to %. Silver The electrolytic silver refining process includes a crude silver anode and a refined silver cathode.

Our electrolytic machines take what is typically multistep process dangerous process and turn it into a singlestep procedure that can be done quickly, easily, and without the presence of dangerous or irritating fumes. Smelt your low karat gold, place in to the system, wash refined 24K gold, use it.
The Wohlwill process increases purity to about percent by electrolysis. In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride. Under the influence of an electric current, the gold migrates to a negatively charged electrode (cathode), where it is restored to a highly pure metallic state, leaving the impurities as a separate solution or residue.
3/12/2009#0183;#32;GDay to all, I have some 9k, 14k, gold and plated jewellery that I want to use the Wohlwill process on to extract the gold. I watched a video by Steve I think showing a small bath of AR with a lead anode and a multi pronged cathode being used to strip the gold plate from computer parts.
The principle and equipment for gold electrolysis. 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.

In the process of electrolytic gold refining, hydrochloric acid is used as an electrolyte. A thin sheet of gold is made the cathode and a gold alloy is made the anode. When ion transfer takes place a pure gold with higher purity rate is transferred to the cathode. This method is also called as the cycle of Wohlwill.
In gold processing: Refining. The Wohlwill process increases purity to about percent by electrolysis. In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride. Under the influence of an electric current, the casting functions as a positively charged electrode, Read More
Melt your 5K 10K gold and cast an ingot. Place the gold ingot in the unit, fill the unit with electrolyte and turn on the power supply. 1224 hours later, remove the anode section and wash the gold with water. Remove the disposable ashless paper bag with refined gold from the anode section.
Invented by Emil Wohlwill in 1874, this produces the highest purity gold (%). It is an electrolytic process using pure gold for the cathode (or titanium as a starter cathode) and chloroauric acid (gold chloridehydrochloric acid) as the electrolyte; this is made by dissolving gold with chlorine gas in the presence of hydrochloric acid.
