#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.
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
This refining plant is used to obtain gold with purity of 999,9 (thouhs)using gold alloy anodes with a gold content of approx 990995 dismountable to allow cleaning operations and recovery of the gold chloride deposited inside the pipes during the electrolytic refining process.
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 (Ault;3+gt; 80120g/L) and low acid (6090g/L) with a titanium motherboard used for replacing a traditional gold starting sheet as a cathode.
The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold.

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.
The method just described aims at leaving gold in an insoluble state at the anode. Other impurities are usually left there, and the gold sponge, or slimes, needs further refining by methods, to be indicated later. By using a suitable electrolyte the gold can be dissolved from the anode bars and deposited in sheet form on the cathode, while many metals can be left in solution. The active agent
Electrolytic refining of gold the method just described aims at leaving gold in an insoluble state at the anode other impurities are usually left there, and the gold sponge, or slimes, needs further refining by methods, to be indicated later Gold refining by electrolysis process 171; gold international.
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.

Our patented, electrolytic system makes the entire goldrefining process easy and simple; what has long been a lengthy, multistep process, you can now complete with
The electrolytic refining technique allows to yield high purity gold /1000. Our systems are designed and manufactured to run the process efficiently and safely. The process efficiently works when the input material is minimum 980/1000. The ouput of the electrolytic refining process is pure gold
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.

Gold electrolysis requires small amount of chemicals and labor. It is, in fact, environmentally friendly. However, it is a very expensive procedure because a permanent stock of gold is required to run the electrolytic process. Take for instance, for every gold produced through
