DetailsPre-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.

DetailsThis will make the bond between the molecule and the bubble as well as the bond between the particle and the molecule weak. Both will begin to fall free of the bubbles. As these particles that do fall off descend into the cell they become trapped by the tighter smaller bubbles that are caused by the pressure of the slurry in the cell.
