Gold ore extracted from mines in the earth contains a significant amount of impurities, including traces of other metals. In order to separate the gold from other metals, chemicals such as cyanide solution or mercury are introduced to the gold. This process causes the gold to coagulate, and form nuggets and clumps of gold.

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. The Miller process is rapid and simple, but it ...
For example, diamonds were found in Kimberley and gold ore was found in Johannesburg. . In ancient times mining and mineral processing were very primitive and the main. Contact US Processing, smelting and refining World Gold Council. The most common techniques to refine and process gold ore are the Wohwill and Miller processes.
Miller's Gold Chlorination process was introduced by F.B. Miller. The refining process employs chlorine gas, which passed into molten gold covered with a layer of borax and silica, and reacts with most of metals present in the molten charge. Platinum group metals do not react. Basically, gold is slightly attacked in the first moments and all the chlorides formed rise to the surface and are ...
The Miller process is an industrial-scale chemical procedure used to refine gold to a high degree of purity (99.5%). It was invented by Francis Bowyer Miller (patented 1867). This chemical process involves blowing a stream of pure chlorine gas over and through a crucible filled with molten, but impure, gold. This process purifies the gold because nearly all other elements will form chlorides ...

The complexity of this processing depends in part on the grade of the ore. Low-grade ore is relatively simple to process while high-grade ore is a more extensive and complicated process. Completing Off-Site Refining; Once the initial processing is done on-site, the gold is transported to an off-site refinery to undergo further refining.

Gold Refining. Gold mines process ore using various techniques to produce an alloy composed primarily of gold and silver, which is called a dore bar. The composition of dore can vary significantly between mines, but generally the gold dore bars the Perth Mint processes are composed of between 70-80% gold and 10-15% silver.
