Electrowinning Anodes ULTRANODE
In electrorefining, the anodes consist of unrefined impure metal, and as the current passes through the acidic electrolyte, the anodes are corroded into the solution so that the electroplating process deposits refined pure metal onto the cathodesThe anodes are only 4mm in thickness, and are eaten away in 24 hours, the cathodes are made of thin rolled gold sheets The distance between the electrodes, with an impure electrolyte, is 3/8 inch This process, as stated by Dr Rose is specially applicable to the refining of platiniferous goldElectrolytic Refining of Gold

Anode : 2H₂O → 4H+ + O2 + 4ē¯ In cyanide solutions, gold is present as a stable aurocyanide complex anion with a relatively high cathodic potential (E0) The cathodic shift demands a higher cell voltage and consequently other cathodic reactions like the formation of H2 and the reduction of O2 can also occurMore About Gold – Gold and silver mines for sale, lease, or joint The anode dissolves, and the impurities either pass into solution or report to the bottom of the electrorefining tank as an insoluble Why just buy Gold when you »More detailedbuy anode for electrorefining gold Mining

Electrorefining – Electrolytic Gold Recovery | Gold Refineries
Electrorefining is a process that uses the principals of electrolysis to recover gold from an alloy typically found in jewelry 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 995% pureIn electrorefining, the anode consists of a metal that is not pure, and will then pass a current through the anode which corroded acid electrolyte into the solution so that the electroplating process deposits refined pure metal to the cathodeElectrowinning For Gold Mining Basic Processing Of Gold

CNA Cathode gold electrolytic refining
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 (Au<3+> 80120g/L) and low acid (6090g/L) with a titanium motherboard used for replacing a traditional gold starting sheet as a cathode01011999· Unfortunately, the usage of permanent anodes has the disadvantages of ongoing maintenance costs to clean the anode surfaces and refurbish the wetted area, results in lower anode useful life, the expense of anode replacement, lower current efficiency, higher power consumption as compared to electrorefining, and inferior cathode quality which becomes contaminated due toAnode effects in electrowinning ScienceDirect
