This study systematically investigated the effect of Fe<sup>3+</sup> on barite flotation and its adsorption mechanism using a multidisciplinary approach combining flotation experiments, X-ray diffraction (XRD), Zeta potential measurements, Fourier transform infrared spectroscopy (FTIR),X-ray photoelectron spectroscopy (XPS), solution chemistry calculations, adsorption capacity determination, and contact angle analysis. The results demonstrated that Fe<sup>3+</sup> inhibits barite flotation when sodium oleate is employed as the collector. This inhibition arises from the formation of a Ba(-O-Fe-OH) complex on the barite surface, which reduces the available adsorption sites for sodium oleate. This reduction in sodium oleate adsorption diminishes surface hydrophobicity, thereby deteriorating barite floatability.</div></div>","PeriodicalId":7232,"journal":{"name":"Advanced Powder Technology","volume":"36 10","pages":"Article 105039"},"PeriodicalIF":4.2,"publicationDate":"2025-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144878413","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}

In this research, a recently developed transient-state multifluid BF model is applied to elucidate the temporal evolution of in-furnace phenomena. Besides, a domain-average method is adopted to analyse the extensive simulation data to determine the time required to attain the next steady-like state. The results show that the evolution of thermal and chemical conditions varies across different regions, with distinct characteristics near the furnace wall. The shifts in iron oxide reduction behaviour are completed within 10 to 20 h after the new operation, and the transition time points to the next steady-like states of thermal and chemical conditions are different. As the hydrogen flow rate increases, the average transition time decreases. However, 2 to 4 days are required for the studied BF to reach a new steady-like state in the considered scenarios. The model offers a cost-effective approach to investigating the transient smelting characteristics of an ironmaking BF with hydrogen injection.</div></div>","PeriodicalId":7232,"journal":{"name":"Advanced Powder Technology","volume":"36 10","pages":"Article 105040"},"PeriodicalIF":4.2,"publicationDate":"2025-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144878502","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}

However, the utilization of nanoparticles is often hindered by particle loss during transfer. In this study, we developed a predictive model for the penetration efficiency of aerosol in the three-turn coil with conductive (Copper and Tygon) and non-conductive (Teflon) materials. We conducted samplings for NaCl particles under controlled conditions and atmospheric aerosol particles directly from the ambient environment. The results demonstrated that penetration efficiency strongly depends on coil material, with non-conductive Teflon exhibiting significant particle losses due to electrostatic effects. Comparative analysis with existing models revealed their limitations in capturing the coupled influence of diffusion, secondary flow, and electrostatic effects in multi-turn coil configurations. To overcome this limitation, we developed a novel predictive model incorporating a new parameter (<em>Γ</em>), which enables accurate estimation of nanoparticle penetration efficiency in multi-turn coils under the broadest operating conditions. By accounting for electrostatic forces, our model is applicable to both conductive and non-conductive coil types, achieving the highest accuracy, with average errors of 9.37% for conductive and 5.97% for non-conductive coils.

This method effectively reproduces the complete stress–strain process of red sandstone under uniaxial loading. Furthermore, the acoustic emission (AE) characterization technique in PFC was enhanced through optimizing spatiotemporal clustering criteria and localization algorithms for microcracks. The rationality of this approach was validated by analysing AE energy characteristics and the correlation between microcracks and macroscopic fractures. To accurately identify the spatial distribution and threshold stress of microcrack nucleation, a full-field synergistic strain calculation method and local strain concentration coefficient (LSCC) for PFC based on digital image correlation (DIC) were proposed. The results demonstrate that strain information exhibits higher sensitivity compared to fracture information, and the LSCC effectively identifies threshold stresses corresponding to microcrack nucleation and rock failure.

Using data augmentation to enhance model robustness, the architecture achieves good accuracy (R<sup>2</sup> > 0.85) for PSD predictions and 0.82 for viscosity predictions. The model successfully captures process dynamics, including transition points where particle size reduction below 400 nm triggers significant rheological changes.
