Optimal conditions for particle-bubble attachment in

2017-11-1 · Mineral flotation is a process used in the mining industry for separating solid particles of different sizes and densities. The separation is done by injecting bubbles into a slurry where the particles attach to them, forming floating aggregates. The attachment depends mainly on the bubbles and particles sizes as well as the hydrophobicity and roughness of the particles.

Particle-bubble attachment in flotation froths

Particle-bubble attachment in flotation froths Results indicated that the probability of attachment increased with an increase in the hydrophobicity of the draining particles, an increased bubble frequency and an increased gas holdup. It decreased when the coating of bubble surfaces was increased by the addition of fine floatable material.

2020-9-20 · 1. Introduction. Flotation of low-rank coal is an important task for the mineral processing researchers in the world [1,2].Due to the high porosity and strong hydrophilicity of low-rank coal particles [3,4], the wetting of water to these pores increased when low-rank coal immersed in water [].Xia and wang [] found that the yield of clean coal decreased as the pre-wetting time increased.

Variations in the induction period for particle-bubble

The success of flotation is governed by particle-bubble attachment. A convenient means of predicting the attachment compares the duration of sliding 'contact' with the induction time. Whereas a number of theoretical models and empirical correlations exist for evaluating the 'sliding contact' time, comparatively little is known about the key

Mechanism and research progress of the bubble

The interaction process between particles and bubbles can be classified as collision, attachment, and detachment; all three sub-processes determine the collection probability between particles and bubbles. Upon collision, the hydrophobic particles strongly attach to the rising air bubbles, which carry them to the surface, thereby overflowing the flotation cell in the collecting launder.
