Gold was primarily collected from alluvial deposits in the ancient world using gravity techniques and mercury (amalgams), which are still employed today in small-scale alluvial gold resources. Large-scale hard rock mining first employed cyanide in the 1880s to extract commodities, including gold, silver, copper, and other precious metals [ 7 ].
