Flotation and Recovery Processes | Graymont

Lime is used extensively in the recovery of gold and silver. Ores, either run of mine, milled, autoclaved, or roasted are combined with lime and a cyanide solution. The cyanide dissolves the gold and silver. Lime maintains proper pH in the cyanide solution, keeping it in the liquid phase and preventing the formation of hydrogen cyanide gas and its loss into the atmosphere.

Recovering Gold through the Froth Flotation Process - MGS ...

Pre-19th century placer mining operations used mercury to dissolve the gold in crushed ore, making it easier to recover. Later innovations include the MacArthur-Forrest Process and borax flux extraction. However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules.
