Add to Compare.The Metallurgy of Cyanide Gold Leaching ,With lower gold grades beneficiation (usually flotation) is often used ahead of leaching to increase the grade of Au and reduce the quantity of ore to be leached. Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant.

Gold extraction - Wikipedia

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.The Metallurgy of Cyanide Gold Leaching ,With lower gold grades beneficiation (usually flotation) is often used ahead of leaching to increase the grade of Au and reduce the quantity of ore to be leached.
