Froth Flotation an overview ScienceDirect Topics

Froth flotation is a surface chemistry based separation process which is extensively used in the processing of mineral ore deposits as a method of separating the desired mineral component from their associated gangue material [17,34]. From: Advances in Colloid and Interface Science, 2005.

Froth flotation of sphalerite: Collector concentration

2014-3-1 · This experimental work on sphalerite flotation investigated the effect on flotation performance of three particle size fractions, namely, coarse (d 80 = 100 μm), medium (d 80 = 39 μm) and fine (d 80 = 15 μm), bubble size distribution, superficial air velocity, and collector dosage. Bubble size distributions were characterized with the image analysis technique.

A Hybrid Device for Enhancing Flotation of Fine

The froth flotation technique can be considered one of the most effective methods for the separation/beneficiation of minerals . Researchers today are paying increasing attention to the flotation of fine particles (45–100 μm) and ultrafine (−20 μm) mineral particles.

2014-9-1 · For the application of froth flotation, hydrophobic and hydrophilic tracers were fabricated to investigate the difference in behaviour between valuable and gangue minerals. The hydrophobic tracer was coated in epoxy resin to withstand the grinding forces inside the peristaltic pump, and silanised silica, to increase the contact angle of the silica to around 60°.

The effect of impeller-stator design on bubble size

2020-10-1 · Froth flotation is the most important mineral processing method in the mining industry, due to its technical versatility and cost-effectiveness (Wills and Finch, 2016). It involves the dispersion of small bubbles of gas inside a flotation tank in order to recover the selectively hydrophobised valuable minerals.
