Abstract ：
Germanium is one of the strategic scattering metals, and recovering a minor concentration of scattering metals from zinc concentrate's leaching solution is an essential resource worldwide. Practically, neutralizing precipitation and the subsequent dissolution are implemented to enrich scattering metals from zinc leaching solution, facilitating further extraction of Ge and others. Silicon poses significant challenges to the efficient extraction of Ge due to their similar chemical property and the inert nature of silica. However, the evolution of the Ge occurrence state, especially its relationship with Si, during the precipitation and dissolution process in zinc hydrometallurgy is unclear, and there is a lack of an effective method to separate Si/Ge. This paper started with a detailed characterization and leaching behavior of Ge-enriched residue obtained from the plant, followed by a systematic investigation of Ge behavior in synthetic Si/Ge binary and Fe/Si/Ge ternary systems. Eventually, options for Ge enrichment from zinc leaching solution and Si/Ge separation are recommended, providing a practical framework for mitigating the negative influence of Si on the extraction of Ge in zinc hydrometallurgy. The significant findings are that Ge/Si are both presumably co-adsorbed by Fe(OH)3 colloids upon neutralization to pH 5 of zinc leaching solution, which could be acid redissolved at the unrealistically high liquid-to-solid ratio of 200/1 at the practically meaningful liquid-to-solid ratio of 5/1, Si concentration is high enough to quickly condense and polymerize, resulting the formation of silica precipitate and permanent encapsulating of Ge into silica; interestingly, the Si-O-Ge bonding becomes weakened with pH increasing up to alkaline region and Ge leaching rate exceeding 80% at pH 10, effectively separating Ge from SiO2. © 2025 Elsevier B.V.

Abstract ：
易选硫化锌矿资源因大量开发而日趋枯竭,以菱锌矿为代表的氧化锌矿资源的高效开发利用愈发重要.菱锌矿与白云石同属碳酸盐类矿物,晶体结构相似,表面性质相近,浮选分离困难.通过浮选试验,系统研究了以油酸钠、十八胺、苯甲羟肟酸、水杨羟肟酸及其组合为捕收剂,四聚磷酸钠和氯化钙作为组合抑制剂条件下,菱锌矿与白云石的浮选特性.结果表明,单一捕收剂体系中,菱锌矿与白云石难以有效分选;水杨羟肟酸和油酸钠的捕收剂组合具有良好的协同效应,四聚磷酸钠与氯化钙的抑制剂组合具有较高的选择性,可实现菱锌矿与白云石的高效分选.采用晶体化学模拟计算、动电位分析、捕收剂吸附量分析等手段,对浮选结果与作用机理进行了阐释与验证.

Abstract ：
The CuO nanorods were in-situ grown on sensing electrodes by a chemical bath method for the detection of volatile organic compounds (VOCs). The synthesized material was characterized by using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and Fourier-transform infrared spectroscopy (FTIR). The CuO nanorods, with lengths of 100-150 nm and diameters of 35-55 nm, were uniformly formed into a thin film on the electrode surface, with a thickness of approximately 1 mu m. The gas test results demonstrated that the sensor achieved a peak response of 1.32 for formaldehyde at 200 degrees C, and a response of 1.92 for ethanol at 175 degrees C. At a concentration of 50 ppm, ethanol and formaldehyde at an operating temperature of 200 degrees C exhibit short response/recovery times of 28 s/ 48 s for ethanol and 45 s/62 s for methanol, respectively, coupled with good reproducibility. Moreover, the sensor exhibited a power-law response to varying gas concentrations and showcased superior selectivity in the VOCs gas detection. This in-situ growing CuO of our work provides a facial gas sensing material fabricated method.

Abstract ：
In this study, the adsorption behavior of gallium ions on a synthesized hydroxamic acid resin from sulfuric acid solution was investigated, aiming to recover Ga directly from pressure leaching solution in zinc hydrometallurgical plant. Hydroxamic acid chelating resin (HA-PDR) was prepared by introducing hydroxamic acid groups into the pre-made polyacrylate resin (PDR) with methyl ester group through hydroxylamine reaction. Polyacrylate-divinylbenzene hydroxamic resins with a nitrogen content of up to 3.85 % were obtained at a divinylbenzene (DVB) content of 13 % and an optimal raw material ratio of NH2OH & sdot;HCl: NaOH: -CH3 = 4:4.5:1 (molar ratio). The obtained materials was characterized using FTIR, XPS and SEM to verify the successful introduction of hydroxamic acid groups. The results of adsorption experiments showed that the adsorption capacity of 27.65 mg/g could be obtained with a chemical, multilayered, and heterogeneous adsorption process, and film diffusion and intra-particle diffusion rate controlled mainly the adsorption efficiency. It has been proven that polyacrylate-divinylbenzene hydroxamic resins has extremely high adsorption selectivity for gallium in sulfuric acid solution, and the desorption effect is obvious, which can be applied promisingly in the industrial development of gallium extraction technology from zinc leaching residue in sulfuric acid system.

Abstract ：
This study investigates the ethanol gas-sensing mechanisms of ZnO nanocrystals with distinct morphologies, synthesized via a hydrothermal method using various alkali sources. Significant differences in the gas-sensing performance and morphology of ZnO samples synthesized with ammonium carbonate (Na2CO3), hexamethylenetetramine (HMTA), ammonia solution (NH3H2O), and sodium hydroxide (NaOH) were observed. ZnO were confirmed to be impurity-free through XRD analysis, and their morphological features were characterized by SEM. TEM, XPS, and FTIR were employed to further analyze the crystal structure and binding energy of ZnO. To elucidate the underlying mechanisms, density functional theory (DFT) calculations combined with electron depletion layer theory were applied to assess charge transfer processes and identify the most sensitive ZnO crystal planes for ethanol detection. Experimental gas-sensing tests, conducted across 5-1000 ppm ethanol concentrations within a 150-350 degrees C range, showed that ZnO prepared with Na2CO3, HMTA, and NaOH was responsive at high ethanol concentrations as low as 100 degrees C, while ZnO synthesized with ammonia required 250 degrees C to exhibit sensitivity. All ZnO samples demonstrated excellent recovery at low concentrations at 250 degrees C. By integrating experimental findings with theoretical insights, this study provides a comprehensive understanding of ethanol gas-sensing mechanisms in ZnO, highlighting the role of crystal plane engineering and charge transfer dynamics as critical factors influencing gas response.

Abstract ：
Sulfurous iron minerals with recovery value are contained in a lead-zinc tailing in Fujian Province, China. However, the sulfurous iron minerals are depressed by lime in the early lead-zinc flotation, therefore it is necessary to use appropriate activators to improve the floatability of the mineral. The property of flotation foam can directly reflect the quality of the flotation index. The addition of activators can also change the properties of flotation foam. In this paper, an effective activator combination was selected through actual mine tests and foam analysis. The mineralogical study of the lead-zinc tailing was first carried out through chemical multi-element analysis and XRD. The flotation tests on the recovery of sulfurous iron ore by different activators were carried out. Finally, a foam scanning analyzer was used to test and analyze the frothing performance and froth stability of the slurry under different activation conditions. The results showed that the dispersion-activation flotation and dispersion-combined activation flotation can help to improve the frothing performance of the slurry and improve the flotation indexes. At the same time, the enhanced activated flotation can also reduce the froth stability indexes (FSI) to less than 20 s, and the reduction of the froth stability can help to improve the flotation recovery. For each activation flotation process that achieves the best flotation index, the frothing performance and foam stability of the pulp is close to that of the flotation tests index.
