    The electrolytic refining technique allows to yield high purity gold 9999/1000 Our systems are designed and manufactured to run the process efficiently and safely The process efficiently works when the input material is minimum 980/1000The most you can get for gold is 9992% that is for single refining and only if you spend a long time putting a lot of nitric acid, usually it's between 9960 to 9980% You can achieve 9999% through electrolytic refining sometime called electrorefining The hard part is silver, if you use copper to precipitate silver nitrate solution, you can only achieve 9940% purity, depends on how you wash it thereafter,Wohlwill electrolytic refining process for goldElectrolysis, 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 dipped in an electrolytic cell containing an aqueous solution of the metal saltElectrolytic Refining Mining Fundamentals

  • Electrolytic processes for gold and other precious metals

    The electrolytic refining process for gold uses hydrochloric acid as the electrolyte 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  Each refining cell can produce from 16 to 20 Kg in 24 hours The electrolyte solution should contain minimum 80 gr/l of gold as chloride  Each plant consists of one or multiple cells, made of selfextinguishing Polypropylene, and resting on a safety tray Each refining cellElectrolytic Gold Refining ItalimpiantiThe present invention relates to an electrolytic gold and silver refining cell for extracting gold and silver contained in a material The cell is part of a plurality of cells arranged in at least one common vessel provided with a solution feeding inlet, an exhausted solution outlet, and a stirrer The cell is also provided with a plate cathode consisting of an acidproof material and a plateUSA Electrolytic silver and gold refining cell
