About This Special Issue
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

    Abstract: Understanding the attachment micro process is a fundamental step toward predicting the rate constant of flotation kinetics. In this research, the effect of bubble-particle attachment efficiency on k-Sb relationship was investigated under Yoon, Stokes and Potential conditions. Maximum Stokes attachment efficiency obtained was 55.9% with particle siz... Show More

    Abstract: The frothers are influence on the ability of bubbles to collect particles from the pulp and carry them to the froth layer. In this study the effect of type and dosage of frothers on bubble-particle collision probability and dispersion of fine particles was investigated. Therefore, collision probability of fine particles was calculated using frother... Show More
