ores can be subjected to further processing to improve the cyanidation-based recovery rate, but often at greater expense. Refractory behaviour in gold ores includes those ores in which the gold is less accessible physically, typically because the gold particles are extremely fine and locked inside a protective layer of material. This

Geology - Gold Mines Desert Mining History Stamp Mill A stamp mill was a mechanical crusher, noisy, heavy and somewhat awkward to operate. The stamps were heavy metal weights that were lifted and dropped on the ore by a crankshaft. The crushed ore would then be further refined, usually by a mercury or cyanide process. The process explained
