Flotation Technology For Coarse And Fine Particle Recovery
A labscale hydrofloat unit for flotation by size of a well characterized sphalerite zns ore awatey et al 20132014 in this comparison the feed was screened to remove minus 250 micron particles the hydrofloat recovery by size was compared with a 15 liter denver mechanical cell under optimized and comparable conditions in.
A new highcapacity flotation technology the stackcell has been developed as an alternative to both conventional and column flotation machines this technology makes use of a preaerated highshear feed canister that provides efficient bubbleparticle contacting thereby substantially shortening the residence time required for coal flotation.
The Hydrofloat Separator A New Technology For
An innovative separator known as the hydrofloat cell has been developed specifically for the upgrading of coarse particles that are difficult to recover using conventional flotation cells the novel characteristic of this separator is the formation of a hindered teeterbed of fluidised solids into which small air bubbles are injected the air bubbles selectively attach to hydrophobic particles.
