Utilizing a batch system with <em>A. niger</em> cultivated in soybean broth we investigated its efficiency in leaching copper (Cu), zinc (Zn), manganese (Mn), aluminum (Al), and iron (Fe) under controlled conditions: initial pH 4, temperature 25 °C, and a solid-to-liquid (S/L) ratio of 1:20 (w/v).

Analytical techniques, including X-ray diffraction (XRD), optical microscopy (OM), Fourier-transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA), confirmed transformations in the mineral phases, with secondary minerals such as oxalates and oxides forming. Field emission scanning electron microscopy (FESEM) coupled with energy-dispersive X-ray spectroscopy (EDS) revealed the degradation of sulfides and carbonates, leading to the formation of oxides and crystallized oxalates on the mineral surfaces.

While current Fe removal methods (e.g., jarosite and goethite precipitation) generate hazardous low-iron wastes, this study presents a novel approach through magnetite precipitation, which offers high Fe content (∼72 %) and strong ferromagnetism for effective impurity separation. We systematically evaluated three magnetite precipitation methods, analyzing their iron-removal products, magnetic separation performance, and crystallization mechanisms. Our investigation revealed critical limitations of two conventional approaches: partial oxidation yields large, strongly magnetic magnetite particles but suffers from high nucleation barriers (∼15,000 k_BT) that favor goethite impurities, while coprecipitation exhibits lower nucleation barriers (∼1000 k_BT) but produces ultrafine, weakly magnetic particles that compromise separation efficiency. Building upon our previously established slow-dropping methodology, we demonstrated that this nucleation-controlled approach enables in situ formation of magnetite seeds, shifting the nucleation mechanism from homogeneous to heterogeneous. This innovative approach achieves dual benefits: reduced nucleation barriers and promoted growth of micrometer-sized magnetite mesocrystals. The resulting product demonstrates remarkable improvements, reaching 104.12 emu/g, substantially higher than that achieved by partial oxidation (77.75 emu/g) and coprecipitation (25.12 emu/g). The impurity removal efficiency reached 70 % for Pb and 81 % for Ca, significantly outperforming conventional methods.

Particular attention is devoted to specific technical challenges emerging in the pyrometallurgical processing of TBFS and potential measures for improving slag utilization by developing new routes and promoting process efficiency. Strengthening the directional transformation and migration enrichment of valuable components during roasting is a prerequisite for achieving effective resource utilization.

This study investigated the potential of two anionic polyacrylamide (APAM) flocculants, AN 934 and its higher molecular weight variant AN 934 VHM, to promote NB formation and stability. Remarkably, both flocculants produced NB concentrations comparable to those generated by the conventional anionic surfactant sodium oleate (NaOL), despite exhibiting negligible surface activity and minimal surface tension reduction. Instead, their stabilizing effect was driven by two key mechanisms: enhanced electrostatic repulsion indicated by significantly more negative zeta potentials, and increased solution viscosity which inhibited gas diffusion and bubble coalescence. AN 934 VHM demonstrated superior performance due to its higher molecular weight, yielding greater charge stabilization and viscosity enhancement, and thus more persistent NB populations. These findings reveal an unrecognized capability of APAM flocculants in NB stabilization, opening new avenues for their strategic use in flotation, tailings dewatering and other particle–bubble interaction-driven processes in mineral processing.</div></div>","PeriodicalId":18594,"journal":{"name":"Minerals Engineering","volume":"234 ","pages":"Article 109739"},"PeriodicalIF":5.0,"publicationDate":"2025-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144892213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experimental results demonstrated that gradient elution method achieved a remarkable NH₄⁺ removal efficiency of 1290.0 mg/kg, significantly outperforming single deionized water elution (163.3 mg/kg) or 0.02 MgCl₂ elution (1146.8 mg/kg).

This method generates a substantial quantity of highly alkaline red mud, which possesses significant application potential due to its elevated iron content. However, the iron-bearing minerals in red mud predominantly exist as weakly magnetic hematite, making it challenging to achieve an optimal recovery rate through straightforward physical separation techniques. Consequently, additional treatment is required for effective iron recovery. This paper presents an innovative approach that employs agricultural waste straw as a reductant, facilitating the directional transformation of hematite into magnetite via a one-step dissolution process integrated within the Bayer method framework. This addresses the issue of low recovery rates associated with the weak magnetism of iron-bearing phases in red mud. The transformation process from hematite to magnetite induced by alkali thermal dissolution of straw was examined using X-ray fluorescence spectroscopy (XRF), X-ray diffraction (XRD), and scanning electron microscopy with energy-dispersive spectroscopy (SEM-EDS). During the simulation of the Bayer process for the alkali thermal reduction of hematite, it was noted that increases in temperature and straw quantity significantly enhanced the reduction and conversion of hematite. Specifically, when the caustic concentration of the sodium aluminate solution reached 240 g/L, with a molecular ratio of 3.1, a reaction temperature of 280 °C, a liquid-to-solid ratio of 4:1, and a mass ratio of straw to hematite of 1:4, the reduction rate of iron oxide achieved an impressive 94.21 % after 60 min of dissolution. Analysis using a vibrating sample magnetometer (VSM) and laser particle size analysis (LPSA) demonstrated that the magnetic saturation intensity and average particle size of the transformed magnetite increased by over 80 times and 10 times, respectively, reaching 86.84 emu/g and 20.73 µm, thus enhancing its susceptibility to separation by magnetic force in subsequent roughing processes. Scanning surface zeta potential analysis (SSZPA) revealed that the absolute values of the zeta potential of the desilication product (DSP), hematite, and transformed magnetite under strong alkaline conditions followed the order: magnetite &gt; DSP &gt; hematite, with magnetite exhibiting stronger repulsive forces. Further scanning tunneling microscopy (STM) analysis indicated that the solvation tendency of magnetite particles was magnetite &lt; DSP &lt; hematite, making them more prone to aggregation and growth during the alkaline thermal dissolution process.
