Gold extraction - Wikipedia
Gold extraction is the extraction of gold from dilute ores using a combination of chemical processes. Gold mining produces about 3600 tons annually, and another 300 tons is produced from recycling. Since the 20th century, gold has been principally extracted in a cyanide process by leaching the ore with cyanide solution. The gold may then be further refined by

The machine, called an arrastre, used a giant stone attached to a wooden arm, moved by a horse, to crush the gold-bearing rock. It was designed to speed up the crushing of the quartz ore. The ore was placed in the bottom of the arrastre over which were placed large rocks. The rocks were ground over the ore, crushing it and releasing the gold.
