The Chinese Journal of Nonferrous Metals, 2018, 28(1): 205-211... structure. Synthesized LiSbF6 crystals are in single-phase with good crystallinity. The molar ratio among Li, Sb and F is accurate, which indicates that the purity of LiSbF6 crystals is extremely high (≥98......
characteristics of the sulfide minerals are greatly affected by the chemical state of their important surface species such as Fe, Cu, S and O [13]. Therefore, in this work, the high resolution spectra of Fe... the treatment with H2O2. Fig. 7 High resolution XPS spectra of pyrite before and after treatment with H2O2 In the high resolution XPS spectra of untreated pyrite shown in Fig. 7, the characteristic peaks......
for preparing α-HH from DH [4]. However, the technology requires high temperature and pressure, and thus is high energy-consuming. In recent years, researchers have conducted extensive experiments... but also causes serious environmental pollution. The preparation of α-hemihydrate gypsum (α-HH) is an important way to achieve high-value utilization of FGD gypsum. Although the glycerol-water solution......
carbon, mineral oxides, biological substances and ion- exchange resins [5]. Although nanomaterials have been recently investigated for removal of various ions [6-12], and have shown high kinetic...; however, its industrial use depends on a high enough adsorption efficiency. Generally, the pH of aqueous solutions may become a major factor in the adsorption of metal ions if it affects......
prospective areas of high potential not only correspond to the areas of known manganese deposits but also provide a number of favorable targets in the region for future mineral exploration. Key words..., leaching, and accumulation process, the primary sedimentary strata acted as the source beds. To reflect the source of metals in the secondary enrichment of Mn, the thickness of Mn sedimentary strata......
