Once the gold has been dissolved in the cyanide, and the ore body has been reasonably depleted of its gold, there are two main processes for recovering the gold from the pregnant cyanide solution. One is the Merrill-Crowe zinc precipitation process and the other is the adsorption of the gold .

Gold Extraction Methods Although new process are being proposed on a regular basis, there have in fact been no dramatic changes in the metallurgical techniques for gold extraction since the introduction of the cyanide process (cyanide leaching or cyanidation) by McArthur and Forrester in .

The gold could not be extracted from this compound with any of the then available chemical processes or technologies. In 1887, John Stewart MacArthur, working in collaboration with brothers Dr Robert and Dr William Forrest for the Tennant Company in Glasgow, Scotland, developed the MacArthur-Forrest Process for the extraction of gold ores. By ...

By 550 B.C., the Greeks had started mining the Mediterranean and Middle East for gold. The Romans continued the practice, introducing sophisticated techniques, such as hydraulic mining, or hushing, which involved using large volumes of water to dislodge rock and remove debris. They also minted coins on a scale never before seen, producing millions of gold aureus coins, each stamped with the ...

Process mining can reveal bottlenecks, deviations, and possibilities for process improvements. Therefore, it is vital to visualize process data in a flexible and highly interactive manner. ProcessGold is able to enrich process mining with customizable visual analytics leading to .

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 produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis.

The addition of gold or silver to an alkaline sodium cyanide solution will cause the gold and silver to react with the cyanide and dissolve into the solution in a process called cyanidation. This process is more frequently referred to as leaching. As well as reacting with the precious metals, the cyanide will react with iron, copper or zinc that may be in the ore.
