Flotation process, in mineral treatment and mining, process for concentrating the metal-bearing mineral in an ore. Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface. The waste material (gangue) settles to the bottom. The froth is skimmed off, and the water and chemicals are distilled or otherwise removed, leaving a clean concentrate. The process, also called the froth-flotation process.
In this special issue, we invite researchers and authors to submit original research and review articles on flotation technology. Potential topics include, but are not limited to:
1. Flotation chemistry 2. Sulfides flotation 3. Hydrodynamics of flotation 4. Rising bubbles hydrodynamics 5. Bubble-particle interactions 6. Fine particles flotation 7. Coarse particles flotation 8. Thermodynamics of flotation 9. Kinetic of flotation 10. Special applications for flotation 11. Application of flotation in recycling and environment
