Water quality effects on flotation Impacts and

UV/VIS Spectrophotometry was employed to measure residual xanthates in key process streams and process return water from the Tailings Storage Facility. This allowed the implementation of dosage

Removal of the residual xanthate from flotation plant

It has been estimated that about half of the organic reagents (including xanthate) added to the flotation circuits are consumed while the remaining half are discharged into the plant tailing. The residual xanthate in the flotation tailing can cause environmental issues through contaminating of the nearby water resources as a result of poor design of the tailings dams.

Process effluents and mine tailings sources effects and

Increasing population levels growing economies rapid urbanization and changes in consumption patterns have increased the demand for raw materials such as base and precious metals leading to growing concerns regarding their availability and the global efficiency of the mine supply chain. Mine tailings consisting of process effluents that are generated in a mineral processing plant are

Online determination of residual collector concentration

quantity of collector chemicals in nickel flotation tailings at a concentrator plant with the developed online CE method. Sodium ethyl xanthate and sodium isopropyl xanthate residuals were found in the tailings and slight correlation between the measured concentrations and the

Water quality effects on flotation Impacts and control of

Measurements of the xanthate concentrations in the process water recycled from the tailings pond and two plant slurry tailings samples was initiated in March 2017 for the purposes of monitoring and control. Fig. 9 shows the residual xanthate measurements from March to date. It can be seen that owing to summer conditions dilution from water release during the spring melt and the increased raw water intake for mill motor cooling systems

Removal of the residual xanthate from flotation plant

The residual xanthate in the flotation tailings can cause environmental issues. HBe and AlBe were synthesized and used for removal of the residual xanthate. At optimum conditions more than 99% of the residual xanthate was removed. The kinetics isotherm and thermodynamics studies were conducted.

Xanthate Wikipedia

Xanthate usually refers to a salt with the formula ROCS 2 M + (R = alkyl M + = Na + K +) thus Oesters of dithiocarbonate.The name xanthates is derived from Greek ξανθός xanthos meaning yellowish golden and indeed most xanthate salts are yellow.They were discovered and named in 1823 by Danish chemist William Christopher Zeise.These organosulfur compounds are important in

The Environmental Fate of Flotation Collectors in Mineral

The results obtained give some insight into the environmental fate of ethyl xanthate in tailings streams and a basis on which to consider the environmental importance of such species in tailings
