Xanthate solutions of pH 6-10, prepared from "aged" potassium ethyl xanthate crystals, KEtX, were investigated spectrophotometrically in the region 190-400 mp and showed coexistence of xanthate ions, EtX-, dixanthogen, (EtX)z, and carbon disulphide, CS2. Optical density measurements on the spectra of dixanthogen solutions led to the evaluation ...
1 de ene. de 2021 · In this paper, the degradation kinetics of xanthate in homogeneous solution as a function of pH at 5°C, 20°C and 40°C is systematically studied by UV-Visible spectrophotometric measurements.
5 de abr. de 2024 · To investigate the effect of the initial xanthate concentration on the COD and TOC removal for xanthate solutions with varying carbon chain lengths, only the initial xanthate concentration was changed to 50 mg/L while keeping other experimental conditions constant. The results are displayed in Fig. 8 b and d. For 50 mg/L alkyl ...
1 de sept. de 2021 · Xanthate has become the main organic pollutant in mine wastewater because of its widespread use as a flotation collector. Multilayer graphene oxide (MGO) exhibits excellent adsorption performance ...
1 de feb. de 2024 · Thus, the use of xanthate in the bulk flotation of Cu-Mo sulfides is generally inevitable (Ge et al., 2013, Chen et al., 2013). However, little attention has been paid to investigating the influence of xanthate on the flotation of molybdenite particles, not to mention the interaction mechanism of xanthate species on anisotropic molybdenite surface.
4 de abr. de 2018 · Xanthates are a group of chemicals typically used in sulphide flotation in mining applications. Common xanthate products are sodium ethyl xanthate (SEX), sodium isopropyl xanthate (SIPX), sodium isobutyl xanthate (SIBX) and potassium amyl xanthate (PAX) Hazards. Xanthates are classified as liable to spontaneous combustion in the Australian ...
1 de ene. de 2015 · The sodium butyl xanthate (SBX) with chemical formular as C 4 H 9 OCS 2 Na, has molecular weight of 172, which is provided by Jinchuan mining plant (⩾82 wt%) and used without any further purification. The molecular structure of SBX is shown as Fig. 1.The concentration of SBX as the sole organic target is 100 mg/L in removal tests.Besides, the concentration of SBX is 1000 mg/L in other tests.
