Feb 06, 2018· One of the earliest methods for extracting gold, salt cementation, was perfected by the Lydian Empire during the Iron Age. Pre19th century placer mining operations used mercury to dissolve the gold in crushed ore, making it easier to recover. Later innovations include the MacArthurForrest Process and borax flux extraction. However, one of the most interesting methods is froth flotation.
