18 de mar. de 2023 · Xanthate is the most widely used and effective collector in the flotation of sulfide minerals. However, the residual xanthate in flotation wastewater may cause serious environmental pollution and even human health hazards. At present, a variety of treatment technologies have been developed to degrade xanthate pollutants in wastewater, with the aim of meeting safe discharge standards.
18 de abr. de 2018 · Response surface methodology is used to optimize the leaching process for refractory flotation copper tailings. The proportion of the refractory combination oxide copper (chrysocolla) is 64.84%. At present, few studies have examined the leaching of chrysocolla. In this study, we examine the effects of several variables, including the amount of concentrated sulfuric acid, leaching temperature ...

Sodium salt of ethyl xanthate (sodium ethylxanthate or sodium O-ethyl dithiocarbonate) Structure of a xanthate ester Cellulose xanthate (orange). A xanthate is a salt or ester of a xanthic acid. The formula of the salt of xanthic acid is [R−O−CS 2] − M + (where R is organyl group and M is usually Na or K). Xanthate also refers to the anion [R−O−CS 2] −.
The major reason being the popularity of xanthate usage and the lower cost and easier availability. Market Research Methodology -Perfect through Years of Diligence. Check Research Methodology.

6 de jun. de 2019 · A new methodology for the synthesis of bis (γ-thiolactones) including two different routes was developed. Both strategies are based on xanthate-mediated synthesis involving free radical addition to an unsaturated compound followed by thermolysis and thiolactonization steps. The first approach is based on the addition of a xanthate to different ...
