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.

Electrolytic Refining Mining Fundamentals. Gold The electrolytic gold recovery process employs hydrochloric acid as an electrolyte, a thin sheet of gold with more than % purity as a cathode, and a gold alloy anode. Following the ion transfer, high purity gold is transferred onto the cathode. This process is known as the Wohlwill process.
In the electrolytic precipitation of the gold an iron anode and a sheetlead cathode are employed, the currentdensity being very low, about amp. per sq. metre. The gold is deposited on the lead, and after removal of this metal still contains a considerable proportion of both lead and silver.
The Moebius Process of Purification of Gold by Electrolysis is now in successful operation and is said to be specially suitable for refining copper bullion containing large proportions of silver and gold with small quantities of lead, platinum, and other metals, but is chiefly used in parting dore silver containing not more than 20 per 1,000 of base metals. The apparatus required consists of a
This was introduced on a commercial scale as an adjunct to the cyanide process on the Rand for precipitating the weak and lowgrade solutions resulting from the treatment of slime by decantation, and was known as the Siemens Halske process. The anodes were of sheet iron enclosed in burlap to prevent short circuiting and the cathodes were formed by hanging four or five sheets of lead foil cut

Electrolytic Methods Used in Refining Processes of Gold and Other Precious Metals. Electrolysis is an electrochemical process where an electrical current stream is flowing between two electrodes and through an process involves the transfer of metal ions through the ionised electrolyte solution, depositing positive ions on the cathode and negative ions on the anode.
