Flotation kinetics of coal in the Inflatable Cyclonic Flotation Column

Powder Technology, 2018
This paper mainly investigates the flotation kinetics of coal in the flotation column. The flotation tests were carried out in the Inflatable Cyclonic Flotation Column (ICFC) which consists of two parts, i.e., the inflatable flotation unit and the cyclone flotation zone.

Comparison of flotation kinetics between conventional and home-designed turbulent microbubble flotation cell

International Journal of Coal Preparation and Utilization
Aiming to address the low particle-bubble collision probability in existing conventional mechanical flotation cell, we have developed a home-designed turbulent microbubble flotation cell (HTMFC) to enhance flotation efficiency.

The significance of positive and negative inertial forces in Particle-Bubble interaction and their role in the general flotation kinetics model

, 2021
In this study, a theoretical evaluation of the effect of inertial forces in particle-bubble interactions during the flotation process is presented and supported by the experimental data.

Kinetics and mechanism of coal flotation

Colloid & Polymer Science, 2002
The flotation kinetics of coarse coal particles was studied in a modified version of the Hallimond tube at 25 °C using nitrogen as the carrier gas, in the pH range 2–12. The kinetics was followed by measuring the volume of the particles accumulated in the collector tube as a function of time.

Effect of reagents on flotation kinetics of differently sized feeds

International Journal of Coal Preparation and Utilization, 2021
The particle size and reagents are the most important parameter in flotation performance. Flotation kinetics models are used to define the rate of flotation and ultimate recovery.

Role of surface roughness in the wettability, surface energy and flotation kinetics of calcite

, 2020
The surface wettability and flotation dynamic characteristics of calcite are of great significance for separating it from other coexisting minerals, and the surface roughness plays an important role in the wettability and floatability of calcite ...

Effects of microbubbles and frother types on first-order flotation kinetics of coarse quartz: a Box–Behnken design study

Canadian metallurgical quarterly
This study utilised a Box–Behnken experimental design to examine the influence of various frothers (MIBC, 2-Ethylhexanol, α-Terpineol, and AF-65), dodecylamine (DDA) collector, and microbubbles on coarse quartz flotation performance.

Wettability of non‐metallic inclusions and its impact on bubble‐induced flotation kinetics

International Journal of Applied Ceramic Technology
Ceramic refractory bubbling devices may be applied in the steel ladle to induce the flotation of non‐metallic inclusions to the slag phase. These inclusions have many origins along the steelmaking process and induce a detrimental effect on the mechanical

Flotation Kinetics and Fine Particle Flotation

2004
As with all physical and chemical processes flotation is a rate process governed by kinetic parameters, which are determined by several factors including the chemistry of the mineral-water interface, particle-bubble collision efficiency, and the strength of attachment of particles to the bubbles.

Experimental Studies on the Kinetics of Flotation

1992
Dissolved-air flotation (DAF) is a combination of several physical and chemical unit processes and operations. This study is focused on the phenomena in the flotation tank and especially on the formation and rising of air-bubble floc agglomerates (called agglomerates only).
