In the ancient world gold was mined mainly from alluvial occurrences using gravity methods combined with the use of mercury (amalgamation), a method that is still used today in small-scale alluvial gold mines worldwide. Cyanide, which was first used in the 1880s, is used in large-scale hardrock mines to recover gold, silver, copper, and other metals from porphyry and disseminated ore deposits.
