Industrial application of ammonia-assisted cyanide

The use of ammonia to reduce the consumption of cyanide during the leaching of gold from copper-bearing ores was patented in 1902 by Hunt (1902), during the first period of intense R&D activity in gold metallurgy that followed the invention of the cyanide process by JS MacArthur and the Forrest brothers in the late 1880s The ammonia-cyanide process was used commercially by Hunt to treat
