Electrolytic Refining of Gold Mineral Processing and Metallurgy

The anodes are only 4mm in thickness, and are eaten away in 24 hours, the hodes 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 gold.

Electrolytic processes for gold and other precious metals Nutec

The Electrorefining Process. There are two main types of electrolytic processes, called electrorefining and electrowinning. Both processes use direct electrical current whereby pure metal is deposited at the hode. Electrorefining is the preferred method as an electrolytic process for gold and other precious metals.

Electrorefining Electrolytic Gold Recovery Gold Refineries

Electrolytic gold recovery begins with a bath of hydrochloric acid, which forms the electrolyte. The hode 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.

That will be quoted separately. the condenser is also equipped with a counterwash system that allows total recovery of the gold chloride deposited inside the condenser formed during the fumes suction of the electrolytic refining process. The fumes exit pipe from the condenser is 160 mm complete with butterfly valve.

Electrolytic Refining: Silver Gold Copper

The electrolytic process of goldrefining possesses three advantages that are important in mintwork. First, it produces purer gold than the old processes. The elimination of the last trace of silver from the gold removes the brittleness from the ingots used for coinage, so that they roll and press much better than alloys of the same fineness

Electrolytic Refining of Minerals. The electrolytic refining processes of certain major minerals are discussed below: Gold. In the process of electrolytic gold refining, hydrochloric acid is used as an electrolyte. A thin sheet of gold is made the hode and a gold alloy is made the anode.

The key techniques used in this regard include Cupellation, Fizzer Cell, Miller Process, Wohlwill Electrolytic Process, Pyrometallurgical Process, Aqua Regis Process, and Inquartation and Parting. Experts use the Wohlwill Electrolytic Process only when the initial gold content is around 96.

A variant of the Wohlwill electrolytic process, the Fizzer cell process is suitable for jewelers smallscale refining operations. In the electrolytic cell, the hode is contained within a porous ceramic pot, which acts as a semipermeable membrane it prevents gold dissolved in the electrolyte on the anode side of the wall from passing
