Pyrite Tailings Recovery by Flotation

The Pyrite Tailings Flotation Circuit Flowsheet Initial treatment of the tailings preparatory to pyrite recovery depend upon the source and particle size of the material to be treated. Fine material, such as flotation tailings, normally does not require size reduction prior to pyrite flotation.Froth flotation - Wikipedia,Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.Recover Sulfide Concentrate Tailings by Flotation,The tailings can contain as much as 50 pct Co originally present in the mined ore. Researchers at the U.S. Bureau of Mines have successfully tested on a continuous basis a process that recovers a bulk sulfide concentrate from mill tailings. The concentrate contains up to one-half of the Co and from 50 to 90 pct of the Pb, Zn, and Cu.

Unconventional column flotation of low-grade gold fine,

The treatment of flotation tailings is today a subject of interest in mineral processing because of the potential of wasted materials as an actual mineral resource and because of environmental reasons. Millions of tons are today dumped or being rejected as flotation tailings.Unconventional column flotation of low-grade gold fine,,The treatment of flotation tailings is today a subject of interest in mineral processing because of the potential of wasted materials as an actual mineral resource and because of environmental reasons. Millions of tons are today dumped or being rejected as flotation tailings.Treatment of Old Pyrite Flotation Tailings for Recovery of,,indigenous culture obtained from the pyrite tailings was used as an inoculum for the biooxidation experiments. The pulp density was maintained at 20% (w/v). The effects of temperature, pH, and duration of the biooxidation of old pyrite flotation tailings on the recovery of gold by carbon-in-pulp cyanidation were investigated.

Kinetics Studies on Effect of Recycled Water on Flotation,

Improved flotation kinetics in first recycling of Melbourne and deionised waters were observed. Three recycles of mine water in the flotation process indicated a steady-state rate for copper tailings. This was not valid for Melbourne and deionised waters where flotation wasCopper Flotation | Eriez Flotation Division,copper flotation EFD is the leading supplier of with over 170 installations worldwide.
