Gold extraction . 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 ...
Gold extraction refers to the methods used to remove gold from its raw state in gold ore. A number of processes are employed to achieve extraction, including separating the gold from its surroundings by physical force, exposure to heat, or chemical means. The ore is typically mined first, though this is not always necessary, and then subjected

The rock must contain enough of the metal compound, hence enough of the metal, to be worth exploiting the ore reserve and extract the metal by physical and chemical processes. Low grade ores are usually uneconomic to mine and process, but high grade ores have a high enough metal content to be worth mining and extracting the metal.
