Abstract ：
碳酸锶是维持锌电解顺行的关键添加剂之一.通过盐酸浸出含锶阳极泥获得含锶浸出液,进一步添加碳酸钠析出碳酸锶,实现了从含锶阳极泥回收碳酸锶并返用于锌电解液的新工艺.探究了反应温度、反应时间、液固比、碳酸钠添加量等条件的优化.在浸出温度65 ℃、浸出时间3 h、液固比30 mL/g、碳酸钠添加量为硫酸锶摩尔量的1.5倍时,阳极泥中锶的回收率为37.6％,所获碳酸锶产品含锶42.9％(等同71.5％SrCO3),主要杂质为锌、锰.考虑到Zn2+及Mn2+均为锌电解液的主要离子,因此在所获碳酸锶产品作为添加剂返用于电解液时上述杂质不会对电解过程造成负面影响.研究结果有望为锌冶炼阳极泥中锶资源的回收利用提供参考.

Abstract ：
Efficient removal of iron and aluminum impurities is critical for the extraction of lithium and rubidium from zinnwaldite, a lithium-bearing mineral. In this study, solvent extraction using P507 was employed to remove iron and aluminum from zinnwaldite leaching solutions. However, stripping iron from the organic phase proved challenging due to the strong interaction between iron ions and the extractant. To address this, a novel reduction stripping method was developed using ascorbic acid (AA) as a reductant. This method exploits the reduction of Fe3+ to Fe2+ in the aqueous phase, weakening the binding between iron ions and the organic phase, thus enabling efficient stripping. The optimized process achieved over 99.99% removal of iron and aluminum impurities. Subsequently, rubidium was selectively extracted using t-BAMBP, with a total recovery rate of 88.53%. Scaling-up experiments confirmed the feasibility of the process for industrial applications, demonstrating high efficiency and reagent recyclability. This study offers a promising approach for the efficient extraction and separation of valuable metals from zinnwaldite, with potential for broader applications in metal processing.

Abstract ：
The novel amidoxime-based collectors, 4-pyridylamidoxime (PA), 3-ethyl-4-pyridylamidoxime (EPA), and 3methyl-5-tert-butyl-4-pyridylamidoxime (MBPA), were introduced in the lead-free flotation separation of wolframite from quartz and calcite. Compared with PA, EPA, and the traditional collector benzohydroxamic acid (BHA), MBPA exhibited a better separation and recovery capacity to wolframite ore. 4.0 x 10(-4) mol/L MBPA recovered more than 80 % wolframite, similar to 24 % calcite, and similar to 26 % quartz at pH 8.0 without Pb2+ ions. Under the same conditions, BHA only floated out less than 35 % wolframite. The adsorption amount results exhibited a stronger adsorption ability of MBPA than BHA on wolframite surface. Further, the results of zeta-potential, FTIR, XPS and density functional theory (DFT) calculation revealed that MBPA could chemisorb on wolframite surface to form -N-Fe and -O-Fe bonds. MBPA had stronger electron-donating ability and weaker electron-accepting ability than BHA, which exhibited higher reaction activity. It was clear that MBPA was an excellent collector in the lead-free flotation separation of wolframite from calcite and quartz.

Abstract ：
Copper foil roughness is widely regarded as an important factor affecting the performance of lithium-ion batteries, but relevant research still lacks systematic and in-depth analysis. In this paper, 6 mu m copper foil is prepared by electrodeposition and compared with purchased 6 mu m copper foil. The influence of different roughness on the battery performance is analyzed by the distribution of relaxation time (DRT). The results show that the roughness of homemade copper foil (1.69 mu m) is slightly higher than that of purchased copper foil (1.53 mu m). The initial charging specific capacity of the homemade copper foil electrode reaches 372.51 mAh g-1, significantly higher than that of the purchased copper foil electrode (323.89 mAh g-1). DRT is used to analyze the electrochemical reaction kinetics of the batteries, it is found that the copper foil with a certain roughness can enhance its binding with the active substance, ensure stable and rapid conductive contact, reduce the side reaction caused by uneven lithiation, and minimize the increase in the impedance of each part during the electrode cycle, thereby ensuring stable battery operation. This study provides new insights into the application of copper foil in batteries and verifies the feasibility of homemade 6 mu m copper foil.

Abstract ：
Introducing a conductive carbon layer between the copper foil current collector and silicon active material effectively mitigates electrode damage and battery capacity loss caused by uneven silicon expansion. In this study, a low-cost, environmentally friendly carbon-coated copper foil (CCF) is designed using zeolitic imidazolate framework 8-derived carbon (ZPC) as the carbon source, polyethylenepyrrolidone (PVP) as the binder, and deionized water as the solvent. The large surface area and porosity of ZPC effectively accommodate the volume expansion of silicon, thereby enhancing the overall performance of the battery. The bare copper foil electrode experiences rapid decay, with a failure occurring after just 75 cycles at 0.5 C. In contrast, the CCF electrode maintains a reversible capacity of 576.8 mAh/g even after 200 cycles. The CCF electrode demonstrates superior specific capacity and cycle stability in both the rate and cycling test. According to the relaxation time distribution (DRT) analysis, the porous carbon layer on the CCF surface ensures excellent electrical contact between silicon and the Cu foil during cycling, facilitates uniform lithium insertion into silicon, prevents uncontrolled growth of the SEI layer, and guarantees stable battery operation. This CCF preparation process provides a promising solution to mitigate the degradation of battery performance caused by silicon expansion.

Abstract ：
Electroplating gold coating is very important for both jewelry industry and fabrication of functional materials. The traditional process for gold plating is fulfilled in the cyanide-containing solution, which can potentially produce hazardous HCN gas during electrodeposition and generate hazardous CN--containing wastewater. In addition, the residual CN- ions in substrate can damage the post-coated microelectronics. Cyanide-free processes for electroplating gold are springing up these years, showing great potential for replacing the environmentally unfriendly cyanide process. In this review, the types of gold coatings are first summarized. Then the physicochemical properties of various cyanide-free complexing agents for electroplating gold film are compared. Subsequently, cyanide-free systems that have great potential for industrialization are introduced, with other novel cyanide-free systems still on its infant being also suggested. Finally, the existing problems and future developments are anticipated. The contents can hopefully provide comprehensive understanding of the cyanide-free gold electroplating process.

Abstract ：
Talc is a layered silicate mineral with pronounced crystal anisotropy, consisting of a basal (001) surface and an edge (100) surface, which complicates its separation from valuable minerals. In this study, tannic acid (TA) was used as a depressant, and its adsorption behaviors on the two representative surfaces of talc-silica (basal plane surface) and magnesium silicate (edge surface)-were systematically investigated using experimental methods and molecular simulations. TA addition reduced the contact angles of the talc basal and edge surfaces by 30.5 degrees and 22.7 degrees, respectively, indicating enhanced hydrophilicity. ToF-SIMS analysis revealed that TA physically adsorbs onto the silica surface, while both physical and chemical interactions occur on the magnesium silicate surface. AFM showed lumpy adsorbate on the silica surface and point-like adsorbate on the magnesium silicate surface, with a greater roughness change observed for the former. QCM-D measurements confirmed that TA formed a multilayer flexible adsorbate on the silica surface and a dense, rigid monolayer on the magnesium silicate surface. Molecular dynamics simulations further revealed that van der Waals interactions dominated TA adsorption on the (001) surface, while electrostatic interactions prevailed on the (100) surface. These findings provide insight into the selective depression mechanism of talc and offer guidance for the depression of other layered silicate minerals.

Abstract ：
Conventional silver powder production routes, which reduce silver nitrate solution in the presence of a polymer protective agent, complicate subsequent powder cleaning and wastewater treatment. This study proposes a sulfate-based inorganic protective agent (utilizing Ag2SO4 precursor replacement) that serves dual functions: morphology stabilization and wastewater treatment simplification. This innovation enables the environmentally friendly preparation of sub-micron spherical silver powder. The effects of peristaltic pump flow rate, pH value, temperature, concentration ratio of oxidant to reducing agent on the particle size and morphology of silver powder were systematically investigated. The resulting silver powder exhibited an average particle size of 0.64 +/- 0.05 mu m and excellent thermal stability (weight loss rate < 0.50 % up to 1000 degrees C). Mechanistic analysis via combined XRD, Zeta potential measurements, and density functional theory (DFT) calculations revealed that SO(4)(2- )preferentially adsorbs on Ag(111) facet via chemisorption. Moreover, the production wastewater can be directly treated biochemically after calcium oxide precipitation and air-stripping treatment. Furthermore, the scale-up experiment (single yield 50.0 g) showed that the performance of the experimental product was consistent with the lab-scale results, indicating that the process has good reproducibility.
