Summary: This study investigated the behavior of four ion exchange resins in the selective recovery of vanadium from an acid solution containing iron as an impurity. The chelating resins showed higher selectivity for vanadium, with better fitting to Langmuir isotherm, indicating potential for obtaining pure vanadium solutions in larger scale operations. Positive values of Delta H0 indicated endothermic nature of vanadium adsorption, while negative Delta G0 values revealed a spontaneous character of adsorption process for both metals to all resins.

Summary: The aim of this investigation was to prepare a geopolymeric precursor from vanadium tailing through thermal activation and modification. The research found that during thermal activation, the vanadium tailing was corroded by sodium hydroxide, forming a sodium silicate coating. When water was added, the sodium silicate coating dissolved and released silicon species, creating an alkaline solution environment. Metakaolin dissolved in the alkaline environment to generate aluminum species, which then underwent geopolymerization to produce a geopolymer with excellent mechanical performance. This investigation improves the feasibility of using geopolymer technology for large-scale and in-situ applications, and promotes the utilization of vanadium tailing and other silica-rich solid wastes.

Summary: In this study, different doses of sodium hexametaphosphate (SHMP) were added as grinding aids in the process of muscovite grinding, and the effect of SHMP on the grinding efficiency of muscovite was investigated. The results demonstrated that the grinding efficiency increased significantly with the increase in SHMP dosage. Various test methods were used to analyze the mechanism of SHMP in improving the grinding efficiency of muscovite. It was found that SHMP physically adsorbed on the muscovite powder, resulting in the destruction of the ordered structure of muscovite crystals, surface roughening, and the appearance of cracks. This improved the pulp environment and dispersion of muscovite powder, leading to enhanced grinding efficiency.

Summary: In this study, the crystal cells of muscovite were optimized using Materials Studio 7.0 software. Some properties of the (002) crystal plane and (131) crystal plane were calculated to analyze their influence on flotation behavior. XRD and flotation analysis revealed that the (002) crystal plane had higher surface energy and was more easily exposed compared to the (131) crystal plane. Simulation results suggested that exposing more (131) crystal planes during the grinding stage can improve flotation efficiency.
