Flotation of Gold and Gold-Bearing Ores - ScienceDirect

Jan 01, 2016  Most problems in gold ore flotation are not connected with floating metallic gold. The flotation recovery of free gold (throughout the text free gold is synonymous with liberated gold) is largely affected by physical constraints such as the shape and size of the gold particles and the stability of the froth.

Recovering Gold through the Froth Flotation Process ...

Feb 06, 2018  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.
