Correlation between Flotation and Rheology of Fine Particle Suspensions

Mohsin Sajjad et al.

Summary: This paper summarizes and discusses previous investigations on the correlation between the rheology and flotation process of fine particle suspensions. The study found that the modeling of their correlations as well as comprehensive contributions of pulp and froth rheology on flotation performance have been studied very limitedly, and comprehensive developments in these aspects are strongly suggested.

Coupling Flotation Rate Constant and Viscosity Models

Mohsin Sajjad et al.

Summary: This study investigated the effects of particle-bubble and particle-particle interactions on flotation efficiencies. The results showed that the presence of fine particles increased the suspension viscosity and negatively affected the flotation performance. The study also proposed a novel approach by coupling the suspension rheology model with the flotation rate constant model, which improved the understanding of the problematic behavior of ultra-fine/fine particles in flotation.

Impact of flotation operational parameters on the optimization of fine and coarse Itabirite iron ore beneficiation

M. Safari et al.

Summary: This paper investigates the impact of operational parameters on the reverse flotation of iron ore using a pneumatic flotation cell. The study concludes that collector and depressant dosage, superficial gas velocity, solids concentration, and feed rate all have significant effects on quartz recovery and hematite loss. The study suggests operating the flotation cell at low superficial gas velocities and solids concentrations, but further research is needed at larger scales to confirm these findings.

Direct hematite flotation from an iron ore tailing using an innovative biosurfactant

Andreza Rafaela Morais Pereira et al.

Summary: The study confirmed the biosurfactant adsorption onto the hematite surface, reducing the surface tension of the water/gas interface with a low critical micelle concentration. In flotation experiments, the iron grade and recovery increased with the flotation stage, showing a positive impact of biosurfactant on hematite flotation.

New perspectives in iron ore flotation: Use of collector reagents without depressants in reverse cationic flotation of quartz

Klaydison Silva et al.

Summary: A new amidoamine collector N-[3-(Dimethylamino)propyl]dodecanamide has been proposed for the reverse flotation of iron ore, showing significant selectivity towards quartz while having less impact on hematite and kaolinite. Surface hindrance effect caused by the structure of the collector on the hematite surface is the most suitable hypothesis for explaining the high selectivity in the iron ore reverse flotation process.

Iron Ore Slimes Flotation Tests Using Column and Amidoamine Collector without Depressant

Lev O. Filippov et al.

Summary: This study focuses on the concentration of iron ore slimes using a novel collector and a flotation column, achieving a concentrate with high iron content and metallurgical recovery. The variability of slime characteristics affects the silica recovery, but the applicability of the amidoamine collector has been demonstrated. Further research is needed to optimize the concentration process and stability of silica recovery.

The effects of partially replacing amine collectors by a commercial frother in a reverse cationic hematite flotation

K. Fabrice Kapiamba et al.

Summary: Using a frother as a partial replacement for amine collectors in reverse cationic flotation of hematite can improve flotation performance in terms of grade and recovery. However, higher frother dosages may lead to entrainment of quartz, resulting in higher reagent costs. It would be beneficial to further investigate these findings with alternative reagents and different mineralogical properties in the future.
