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 ：
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 ：
In the zinc production industry using Mn-rich zinc ore, substantial quantities of anodic slime are generated during electrolytic zinc production, containing - 40 % Mn and - 3 % Pb. While a valuable secondary resource, this material poses environmental risks as solid waste. Conventional reductive leaching methods rely on costly reductants and generate high carbon emissions. This study introduces a process utilizing flue gas from zinc plants as a reductant, achieving 92 % Mn leaching efficiency while simultaneously extracting 25 % Sr and fixing 92 % SO2 as sulfate in solution. Kinetic analysis shows a mixed control model with an activation energy of 13.83 kJ/ mol, with reaction rates further enhanced by optimizing gas inlet design. The MnSO4-rich leachate is processed into battery-grade MnSO4 powder, and Sr is recovered as SrCO3, suitable for use as an additive in electrolytic zinc processes. Additionally, NaOH consumption for flue gas desulfurization decreases significantly from 2.14 kg to 0.17 kg per Nm3. Economic evaluation indicates reagent costs represent only 2 % of the total value of MnSO4 and SrCO3 products, offering a sustainable pathway for anodic slime utilization and SO2 mitigation in zinc smelting.

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 ：
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 ：
Electrolytic manganese is an important metal material that is widely employed in batteries, electronics, steel, and other fields. However, there are many issues regarding the production process of electrolytic manganese, such as low current efficiency, high-content toxic SeO2 additives in the electrolyte, and difficulty in controlling the product morphology. These issues not only impact the production efficiency and quality of electrolytic manganese but also result in severe environmental pollution. To address these issues, a MnSO4-(NH4)2SO4 electrolyte system was prepared based on the electrolytic manganese industry standard. The effects of polyacrylic acid, glycine, ethylenediaminetetraacetic acid (EDTA), and gluconic acid were explored as auxiliary additives under neutral electrolysis conditions to lower the SeO2 content, which is a highly toxic main additive. The effects of the different additives on the metal manganese morphology, crystal structure, and cathodic electrochemical polarization behavior were examined by field-emission scanning electron microscopy, X-ray diffraction, and constant current cathodic polarization curve tests. The findings reveal that the main orientation of the metal manganese crystal form deposited by the four auxiliary additives is the (330) crystal plane, and all of them can promote the formation of α-Mn, enhance the electrolysis efficiency, and lower the energy consumption. In particular, the optimized amount of polyacrylic acid of 0.08 g·L−1 contributes to an energy consumption of 5735.34 kW·h·t−1. Correspondingly, the addition of 10 g·L−1 glycine is the most favorable amount, leading to an energy consumption of 5518.56 kW·h·t−1. For EDTA, the lowest energy consumption of 5168.26 kW·h·t−1 is measured at an added amount of 0.5 g·L−1. Note that among the four investigated candidates, gluconic acid is the most favorable auxiliary additive, contributing to the increased cathode current density and reduced cathodic polarization as well as denser metal manganese products. Moreover, gluconic acid addition can lower the concentration of toxic SeO2 from 0.03-0.06 to 0.015 g·L−1, significantly increase the cathode current density, reduce the cathodic polarization, and result in a more dense and smooth product morphology, with the current efficiency being increased from approximately 70% to 89.73% and energy consumption being reduced from 6500 to 4990.58 kW·h·t−1 at the same time. Gluconic acid, as the auxiliary additive, not only contributes to the best electrolysis indexes for electrolytic manganese but also facilitates the formation of metal manganese with the most desirable crystal structure. This work offers novel insights into the environmentally friendly production and cheap electrodeposition of metal manganese for the electrolytic manganese industry. © 2024 Science Press.

Abstract ：
锰电解过程在(NH4)2SO4-MnSO4体系进行时,需维持电解液pH值稳定在7.0～7.2.但阳极析氧反应使得长期电解条件下电解液pH值不断下降.生产上均使用氨水调节电解液pH值.但氨水易挥发,导致整个生产车间氨气味道刺鼻,影响身体健康.此外,持续加入氨水造成电解液中的氨不断累积膨胀,最终产生大量氨氮废水和氨氮锰渣.鉴于乙二胺与氨水的化学性质相似性,且具备更强的碱性及更低的挥发性,探索以乙二胺取代氨水作为pH值调节剂,以减少氨源的使用量、改善作业环境,探究乙二胺新体系电解锰的可行性.
