Operating principles

The Jameson Cell consistently produces fine bubbles and intense mixing between air and slurry. This means fast, efficient flotation. While the principle of using air bubbles to recover particles is the basis of the technology, it is the way air bubbles are generated and how the bubbles and particles interact that make Jameson Cells unique.

Flotation of Gold and Gold-Bearing Ores

1. Background. The application of flotation on a reasonable scale within the gold-mining industry commenced in the early 1930s following the introduction of water-soluble flotation collectors (specifically xanthates and dithiophosphate collectors) that allowed differential flotation of sulfide minerals (Weinig and Carpenter, 1937, Rabone, …

Flotation Equipment

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.

Entrainment of Gangue Minerals in Froth Flotation

Entrainment is a process by which fine and ultrafine particles are transferred to the flotation froth from the top of the flotation pulp, and eventually discharge to the concentrate product, even when they are not attached to gas bubbles. Therefore, entrainment can be considered as a two-step process, one at the upper layer of the pulp …

Adjusting Pulp and Air Levels to Troubleshoot Flotation Cell Froth Movement

Until the pulp level has had a chance to equalize to its pre-set level the froth column will be shallower. Once the slurry is back to its operating level the extra air that was added to the cell is taking up space, this of course will cause the speed that the pulp flows through the cell to increase lowering the effectiveness of the process.
