New technology to improve the recovery of fine particles in froth
01/09/2020 On the other hand, fine particles (<20 µm) are poorly and inefficiently recovered by flotation because of a reduction in the particle-bubble collision probability when the particle size decreases (Reay and Ratcliff, 1973, Trahar, 1981, Sivamohan, 1990, Schubert, 2008).Since fine particles have small mass (and small inertial force), they are deflected by the hydraulic drag

The Challenges and Prospects of Recovering Fine Copper Sulfides
06/05/2022 Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered secondary resources or

Advances in Coarse Particle Flotation Copper and Gold
As a result, flotation circuits are generally configured to process only fine particle size classes in order to maximise recovery in the primary stages. Eriez has invented a novel flotation technology, the HydroFloat, which overcomes these limitations by carrying-out flotation in a dense, fluidised-bed medium allowing for the recovery of coarse particles (>0.250 mm).
