An Electrochemical Flotation Investigation of the Ethyl Xanthate - Jamesonite System

摘要：

The flotation behavior of jamesonite was investigated with ethyl xanthate as a collector. It has been shown that jamesonite has good floatability from pH 2 to pH 12, and relatively poor floatability at pH＞12. The flotation of jamesonite was also dependent on pulp potential at certain pH values. The potential-pH range for jamesonite flotation was established. The FTIR spectroscopy analysis and XPS measurement showed that the major adsorption product of ethyl xanthate on jamesonite was lead ethyl xanthate and antimony ethyl xanthate. The intensity of the FTIR signals of metal ethyl xanthate adsorbed on jamesonite and the flotation response of jamesonite were correlated with pulp potentials.
