The efficiency of the flow channel and a secondary flotation to remove bubbly gases, ink, stickies, and wood extractives were quantified in relation to the reject flow rates or solids yield.

Flotation Cells

Flotation machines can be divided into three classes, comprising respectively mechanically-agitated, air-lift or matless, and pneumatic machines. Minerals Separation Sub-aeration Flotation …

Flotation Innovations Increase Throughput, Recovery

"From that came the nextSTEP flotation machine." Rotor and stator designs were revamped to "outperform other rotor designs available in the global market," he said. "This design has been proven in installations worldwide and is now the standard forced-air flotation machine offering from FLS."

The future of flotation

"The mining industry has a history of addressing dropping feed grades and higher costs by leveraging economies of scale," said Walter Valery, global director of consulting and technology for mining and mineral processing at Hatch. The tendency is to "treat large tonnages, grind all the material finely and let the downstream separation ...

Gold Washing and Gravity Circuit for Processing Placer Gold

As the gravels are discharged to the feed box, water is added and the gravels flow over primary riffles to the washing and scrubbing trommel screen. The primary riffles act essentially as a nugget trap to prevent loss of occasional pieces of gold that might be larger than the ¼-inch opening on the trommel screen.
