The invention provides a cathode gold electrolytic refining process. According to the invention, an electrolyte formula is changed, and electrolytic refining is carried out in a hydrochloric acid system with low gold ion solubility Au3 80-120gL and low acid 60-90gL with a titanium motherboard used for replacing a traditional gold starting sheet as a cathode.Discover More
Electrolytic gold recovery begins with a bath of hydrochloric acid, which forms the electrolyte. The cathode is usually a thin sheet of 24K gold, but it needs to be better than 99.5 pure. The gold alloy source material comprises the anode. This method is called the Wohlwill process.Discover More
2020-7-20The desorption rate is greater than 98 and the recovery of ethanol is greater than 90. The concentration of the rich liquid gold obtained by this method can reach 5-8 g L the gold grade of the char. Therefore, the current efficiency during electrolysis is also higher than other methods.Discover More
2008-3-6Electrolytic 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. We are actually washing it by ammonia. And today through your site I came to know that it is dangerous. Please let me know that how can you recover Gold from that Silver Sludge.Discover More
2017-4-24In 1874, Dr. Emil Wohlwill of the Norddeutsche Affinerie in Hamburg, Germany, developed a method to purify gold through electrolysis. The unpurified gold ore is fashioned into a 100-ounce anode, whereas pure gold strips make up the cathode. The electrolyte solution is a mix of gold chloride and hydrochloric acid.Discover More
2012-3-5Dr. Wohlwills process is based on the solubility of gold but the insolubility of silver in an electrolyte solution of gold chloride AuCl3 in hydrochloric acid. - now i ask - if this is a true method what stops anyone from doing what i first mentioned. Electrolysis for gold.Discover More
2019-7-5Electrolytic refining is the process of extraction of metals metals we can obtain from any refining method using electrolysis. In this method, the anode is an impure metal block from which we are going to extract the metal while the cathode is a block of the same metal with high purity.Discover More
The main part of the recovery and refining technology is the solvent-extraction method, which can refine crude gold into gold of more than 99.99 purity. The method is also used in the extraction of platinum and palladium of more than 99.99 purity. Silver of a JIS equivalent, or higher, in purity is obtained by the refining electrolysis method. 2.Discover More
