Residual Xanthate - Froth Flotation (Sulphide & Oxide ...

The measurement of residual xanthates is difficult to do accurately and reproducibly. Despite this, such measurements have values in diagnostics of process issues. A more general technical solution to control of the dosage of collectors is a feedback loop on the g/t rate from the tailings assays. Other process variables also impact tailings

Removal of the residual xanthate from flotation plant ...

Apr 01, 2018· The residual xanthate in the flotation tailings can cause environmental issues. • H-Be and Al-Be 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.Cited by: 22

Free - Residual Xanthate Measurement in Flotation

I was wondering if anyone is checking into "free Xanthate" or "residual Xanthate" in flotation circuit; specifically in copper flotation.It's more common in Gold leaching to always keep tabs on your "Free Cyanide", but in Copper flotation there is very little interest in knowing what's the residual Xanthate after first rougher, second rougher, etc.

Water quality effects on flotation: Impacts and control

Aug 15, 2018· 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, the xanthate concentration values in the process water ...Cited by: 22

Feb 18, 2015· 高达10%返现· Abstract. The degradation behavior of ethyl xanthate (EX) salt was the most widely used collector in sulfide mineral flotation and emission of flotation tailings with residual EX was harmful to environment. In this work, hydrogen peroxide (H 2 O 2) was investigated by UV-visible spectroscopy (UV/Vis) at different pH values from 3 to 12.

measurement of residual xanthate concentration directly from flotation concentrate cells. Xanthate is a commonly used collector in flotation processes where its residual concentration has an impact on the recovery of metal sulphides. Xanthoprobe has been installed at the Eland Platinum PGM concentrator since March 2010 to establish the long-

The Application of Xanthate in Froth Flotation Process ...

Apr 11, 2019· Xanthate, as the flotation collector with strong collection effect, is mainly used to enhance the hydrophobicity of the mineral surface to meet the requirements of flotation.Xanthate is commonly used in the flotation process of sulfide minerals. Xanthate is a combination of alcohol, sodium hydroxide and carbon dioxide, which is an anionic collector. . It is light yellow, soluble in water and ...

4/6/2009· In some instances, this may also be followed by a filtration step. The result is (a) a moisture-containing mineral concentrate product stream 7 and (b) a return solution stream 9 for the flotation process. The flotation process also produces a tailings stream 11 to which the bulk of the gangue minerals and a portion of the slurry flow reports.
