However, the adoption of coarse particle flotation technology may also carry some drawbacks. Debbie Laney, mining chemicals technical sales manager at Chevron Phillips Chemical Co, says: "For instance, during the flotation process, the recovery of both fine and coarse particles is lower than the recovery of middle-sized fractions.

Flotation Developments Best Practice - International Mining

This is shown in the graph above, which shows flotation recovery by size for a wide variety of mineral systems. This type of pass-band characteristic means that mineral recovery in the fine and coarse size fractions is often sacrificed to get good recoveries in the middle of the size range.

Mineral processing - Wikipedia

These fine bubbles have a higher kinetic energy and as such they can be used for the flotation of fine grained minerals, such as those produced by the isamill. Staged flotation reactors (SFRs) split the flotation process into 3 defined stages per cell and are becoming increasingly more common in use as they require much less energy, air and ...

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Common Questions About Froth Flotation Process Technology

2. Fine-grained minerals have a high adsorption capacity for agents, but their selective adsorption is poor, and their surface solubility is large, which increases the number of difficult-to-separate fine-grained minerals in the slurry. 3. The volume of fine minerals is small and the possibility of collision with flotation bubbles is small.

Effects of fine–coarse particles interaction on flotation ...

Aug 18, 2016  The extended-DLVO theory considering hydrophobic and hydrophilic interactions may be able to explain the fine–coarse particle interactions in flotation processes (Hu and Dai 2003). In this study, the negative interactive effect, especially fine–coarse particle interaction, between different minerals, and its mechanism are investigated.

Jul 18, 2013  Flotation works very well for particles that are typically in the range 20 to 150 μm in diameter, for base metal ores. In this range, it is possible to obtain quite high recoveries in conventional flotation machines. Outside this range, the recoveries decline progressively, whether it is with the very fine or thecoarse end of the size spectrum.
