Recovering Gold through the Froth Flotation Process
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.

The Jameson Cell The Jameson Cell is a high intensity flotation cell in which pulp and air are brought together in a co-current descending flow in a vertical tube called the downcomer. The pulp is introduced into the downcomer through a slurry lens orifice to produce a high velocity jet that generates violent mixing and fine bubble size.
Flotation Cells Design & Operating Characteristics
In its essentials, a flotation cell must provide for two main functions. First, it must supply air adequate in quantity and quality for satisfactory process kinetics. Air quantity can be defined on the basis of the narrow range provided in major U. S. commercial cells, for escape velocity, which averages near 1.2 m/min (4 ft /min).
