Gold cyanidation, also called the cyanide process, is a hydrometallurgical technique for extracting gold from low-grade ore by converting it into a water-soluble cyanide complex; it is the most commonly used leaching process for gold extraction and is also used in silver extraction following froth flotation. The chemist John Stewart MacArthur developed the process in 1887 with the brothers Robert and William Forrest for the Tennant Company in Glasgow, Scotland, achieving up to 96 percent gold recovery by suspending crushed ore in a cyanide solution.
