Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered Column Width: Background: The effect of high intensity conditioning on the flotation of a nickel ore, part 2: Mechanisms.

Minerals Free Full-Text A Review on Froth Washing in Flotation

In the attempt to process lower-grade ores, mineral flotation has taken centre stage as the preferred recovery route. However, in many instances, the froth product does not have a high grade due to the entrainment of gangue minerals. Industry has solved this challenge by introducing froth washing mechanisms. Clean wash water is introduced In the flotation of a copper sulfide ore with magnesium aluminum silicate used as gangue minerals, tests on the relationship between the rheological property of the flotation pulp and the flotation kinetics have found that, when the viscosity coefficient of the flotation pulp increased from 0.002 Pas to 0.02 Pas (at the same time the yield stress Minerals Free Full-Text A Brief Review of Micro-Particle MDPI

Flotation in a novel oscillatory baffled column ScienceDirect

Massey et al. (2012) also reported that even with very low energy input intensity, a high flotation rate could be achieved using small bubbles. In addition, for some agitated column cells where fine bubbles could be generated, it is also found that a high level of agitation or energy input intensity would lower the flotation rate of fine particle Set a new benchmark in high intensity pneumatic flotation by recovering unachievable fine and ultra-fine particles. This results in significant revenue gains as well as minimizes plant operating costs, energy and water consumption per metal production targets.

Improving fine particle flotation using the StackCell™ (raising

A new high-capacity flotation technology, the StackCell™, has been developed as an alternative to both conventional and column flotation machines. This technology makes use of pre-aeration in a high-shear aeration chamber that provides efficient bubble-particle contacting, thereby substantially shortening the residence time Unlike conventional tanks, pneumatic flotation cells are typically classified as high-intensity flotation machines with the capability of floating liberated minerals very fast, resulting in very short residence times, often half that of mechanical cells and a quarter of that of flotation columns (Young et al., 2006).Technological assessments on recent developments in fine and

In addition, the particle size distribution of the recovered mineral showed an increase of about 37.4% in 0–5 μm particles compared to experiments conducted with dispersed air bubbles exclusively.It has been reported that high intensity conditioning produces a high shear force to further disperse collector droplets and particles, causing the collision probability to increase (Engel et al., 1997). This behavior was verified by flotation tests, in which high intensity conditioning increased the flotation rate and recovery (Zhang and Enhancement of coal flotation using impact flow conditioning pulp
