Summary: This study investigated the effect of Cr2O3 content in vanadium slag on its phase composition and micro morphology. The results showed that increasing Cr2O3 content led to a decrease in the grain size of the spinel phase and a homogenization of the distribution of Cr, V, and Ti. Acid leaching experiments demonstrated that after calcification roasting, vanadium and chromium existed in the form of vanadate and (Fe0.6Cr0.4)2O3, achieving complete separation.

Summary: A composite additive roasting and acid leaching process was applied to reduce the vanadium content in vanadium extraction tailings from vanadium-bearing converter slag. The effect of additive with different MgO/(CaO + MgO) ratios on the roasting and leaching behaviors of vanadium slag was investigated, and the optimal process conditions were determined. The results showed that the addition of MgO could transform the vanadate species in the slag, but excessive MgO substitution for CaO reduced the leaching efficiency of vanadium.

Summary: In situ high-pressure Raman spectra of phthalic anhydride (PA) were measured using a diamond anvil cell technique up to 16 GPa. The results showed that all Raman bands shifted towards the blue region with increasing pressure, and new bands appeared. A possible Fermi resonance phenomenon was proposed at pressures above 6.6 GPa, accompanied by a potential first-order phase transition. The changes in Fermi resonance parameters, including intensity ratio, coupling coefficient, and frequency gap of unperturbed transition, were discussed.

Summary: Chemical oxidation as a pretreatment for petroleum-contaminated soil, coupled with bioremediation, can have serious impacts on indigenous microorganisms and available nutrients. This study found that hydrogen peroxide treatments significantly promoted the removal of total petroleum hydrocarbons (TPH), especially in the initial days, and also affected the levels of dissolved nutrients. Both chemical oxidation and nutrients contribute to changes in microbial community structure and diversity. However, the long-term effects of H2O2 as a pretreatment had little impact on the soil indigenous microbial community structure and actually facilitated the continuous removal of TPH by indigenous microorganisms.

Summary: With the assistance of mechanical ball milling, the partially oxidized micro-sponge iron (micro-Fe0@Fe2O3) achieves significantly improved removal of Cr(VI) across a broad pH range. Mechanical force eliminates the surface oxide layer and exposes the Fe0 core, leading to sustained reduction of Cr(VI). The efficiency of micro-Fe0@Fe2O3 is strongly influenced by dissolved oxygen, with higher DO resulting in the generation of stable reductant Fe(II) under acidic conditions, while DO consumption hinders the reduction of Cr(VI) under alkaline conditions due to increased pH. Parameters of ball milling operation, especially rotation speed, have a significant impact on the removal of Cr(VI).

Summary: High molecular weight partially hydrolysed polyacrylamide (PHPA) is commonly used in mineral exploration drilling to increase fluid viscosity and help maintain the suspension of fine particles. However, clarifying these suspensions can be difficult, and previous studies have found that anionic flocculants are ineffective. This study confirmed that nonionic flocculants can successfully aggregate the particles, indicating that the charged tails of adsorbed PHPA prevent anionic flocculants from accessing the particle surfaces.

Summary: Mineral processing requires large amounts of water, and reducing water consumption through recirculation and closing water loops is important. However, this can lead to the accumulation of contaminants in the process water, which can negatively affect the process performance. In this study, the impact of microorganisms on flotation performance was investigated, and ion exchange was evaluated for removing dissolved sulfur species and microorganisms from water. The results showed that adding microorganisms had a positive effect on flotation selectivity, especially for nickel. Different water types, process water and final tailings water, behaved slightly differently. Ion exchange proved to be effective in removing sulfur species and microorganisms, and dissolved air flotation was a successful pretreatment for ion exchange in removing microorganisms.

Summary: This study demonstrates that the use of a DDA/DDTC mixed collector system can significantly improve the flotation performance of smithsonite. The synergistic effect between DDA and DDTC is confirmed, and the mixed collector system contributes to a decrease in solution surface tension. The use of FT-IR and XPS confirms the simultaneous physisorption and chemisorption of DDA and DDTC on the smithsonite surface, and contact angle measurements show that the mixed collector effectively enhances the hydrophobicity of smithsonite. Molecular dynamics simulations reveal the multilayer adsorption of DDTC and DDA on the smithsonite surface, with DDTC promoting the adsorption of DDA.
