There are not one but two common processes for refining gold: the Miller process and the Wohlwill process. Other less common methods are cupellation, inquartation and parting, fizzer cell, aqua regia, and the pyrometallurgical process. According to the World Gold Council, the Miller process uses gaseous chlorine to extract impurities when gold is at its melting point. Impurities separate into ...

In this process the particles of gold remaining in the crucible are carefully removed by hand as well as the separation molds when they have cooled. Once the gold has cooled it is poured through a ceramic filter directly into the granulation equipment or anode molds if the Wolhwill process is .

Generally, gold can be refined using these twobestknown goldrefining procedures: Aqua Regia and gold electrolysis. Both of these techniques can be used to separate gold from other metals. This is because a little piece of other metals in gold can change its properties and value. 1

Refining of Gold at the Rand Refinery Fisher Introduction Since 1921, all gold produced in South Africa has been refined at the Rand Refinery (Adamson, 1972). To give the reader a complete picture of gold refining in South Africa, the historical development and all operations of the refinery are described in detail in this chapter, although some activities cannot strictly be defined ...

· Rand Refinery is currently planning to install golddissolution equipment to allow efficient production of auric chloride solution, utilizing the hydrochloride and chlorinegas process. While the addition of auric chloride solution to the cell will reduce gold sludge make, it will also allow operation at even higher current densities. However, these improvements will not fully optimize the ...

The Miller process is a gold refining process that produces gold of approximately % purity, sufficient for many applications. It is faster and less costly than other refining options used to produce purer gold, which makes it a popular choice at some refineries.

The process is simple and easy. By using our REFINEIT system, all the user has to do is melt the gold in an ingot, submerge the gold in the gold refining equipment we provide, then wait. The next day, pure, 24karat gold will be waiting! Gold Refining Systems not only makes the gold refining, reclaiming process easy, but also clean and safe.

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.

In gold processing: History Miller''s process of refining impure gold with chlorine gas (patented in Britain in 1867) and Emil Wohlwill''s electrorefining process (introduced in Hamburg, Ger., in 1878), it became possible routinely to achieve higher purities than had been allowed by fire refining.

The doré bar first goes through a chlorine refining process, also known as the Miller process – originally developed at the Sydney Mint by Francis Bowyer Miller (see Australian Dictionary of Biography). It involves bubbling chlorine gas through the molten doré metal. Silver (and most other metals) react with the chlorine to form silver chloride as a slag on top. This process produces gold ...
