In this study, a novel Al³⁺/ATMP combined depressant system was developed for the selective flotation separation of cassiterite from calcite using sodium oleate (NaOL) as the collector. Under the selected optimum conditions within the investigated range (pH 9.0, NaOL concentration of 1.75 × 10⁻⁴ mol/L, total Al³⁺/ATMP dosage of 10 mg/L, and Al³⁺:ATMP mass ratio of 1:3), the recovery of calcite decreased to approximately 8%, whereas cassiterite recovery remained around 90%. Surface characterization revealed distinct interfacial responses of calcite and cassiterite to the combined Al³⁺/ATMP treatment. Calcite exhibited a pronounced increase in hydrophilicity, whereas the NaOL-induced hydrophobicity of cassiterite was largely preserved. Residual TOC measurements showed differences in the organic carbon remaining in the supernatants after reagent treatment, providing complementary information on the overall behavior of the reagent systems without distinguishing the individual contributions of NaOL and ATMP. Solution chemistry analysis indicated that the Al³⁺ introduced through aluminum sulfate underwent extensive hydrolysis at pH 9.0, with Al(OH)₃ representing a predominant Al-containing species under the investigated conditions. XPS results revealed the presence of Al- and P-containing species on the treated calcite surface, supporting their involvement in the interfacial modification of calcite and the association of ATMP with the modified surface. Furthermore, under identical simulation conditions, molecular dynamics simulations suggested a greater tendency for the modeled Al(OH)₃ and neutral ATMP species to accumulate near the calcite interface than near cassiterite, accompanied by differences in the relative distribution and mobility of interfacial water molecules. Together with the experimental observations, these qualitative and comparative simulation results support the proposed preferential interfacial association of hydrolyzed Al-containing species and ATMP with calcite, contributing to its selective depression. This work provides an effective strategy for the selective flotation separation of cassiterite from calcite and offers insights into the design of metal ion–organic phosphonate depressant systems for complex oxide mineral flotation.</div></div>","PeriodicalId":271,"journal":{"name":"Chemical Engineering Science","volume":"339 ","pages":"Article 125384"},"PeriodicalIF":5.1,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149201439","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 study, tri-isobutyl citrate (TIBC) was synthesized via acid-catalyzed esterification and characterized by FTIR and ¹H NMR to confirm its structure. TIBC was then blended with Span 80 to construct a miscibility-enhancing system dominated by hydrocarbon chains and oxygen-containing functional groups, referred to as the system (TS), aimed at reducing the MMP of the CO₂-crude oil system. The results indicate that when the mass ratio of TIBC to Span 80 is 3:7 and the total concentration is 1.0 wt%, the system exhibits the optimal performance, reducing the MMP by 18.91%. Analysis of oil droplet interfacial behavior reveals synergistically improved CO₂ dissolution and extraction in crude oil, leading to continuous IFT reduction.

Here we introduce a mixture-aware 3D molecular representation learning strategy, built upon a pre-trained molecular encoder, that jointly encodes component structures, mole fractions, and temperature to achieve accurate predictions for organic mixtures.

Because of this complexity, extracting intrinsic kinetic information, especially with non-collimated lamps, is notoriously difficult, and it is very common to rely on methods of comparative calibration, e.g., actinometry, local measurements of the emissive power of the lamps used, or rigorous computational ray tracing methods. Here, we describe the construction and use of a simple and low-cost cylindrical photochemical chamber that can accommodate various, industrially relevant light sources and spatially integrates radiant flux thanks to a reflective coating applied on its interior walls. By modelling radiation transport at two asymptotic limits, specifically for strongly- and weakly absorbing reaction media, we show that the proposed integrating cylinder can be used with absolute calibration with the help of a macroscopic photon balance. For stagnant reagents and products, one asymptotic case reduces into shrinking core-like reaction when the solutions are opaque, while the other represents a gradientless reaction for dilute solutions. Models reduce to simple mathematical expressions at both limits, whose practical uses are illustrated by two example reactions with different irradiation windows, pyridine photolysis and methylene blue photobleaching. We show that when lamps are well-characterized in terms of their total emissive power, the integrating nature of the chamber allows quantum yield and/or kinetic parameters to be deduced without any additional fitting parameters.

This study uses rigid-body simulation (RBS) to generate annular packed beds of spherical pellets at 52 confinement ratios between 2.25 and 15, with three independent realizations each and a fixed inner radius-to-particle diameter ratio of 2. The generation procedure is validated against annular experimental data comprising an unadjusted radial porosity profile and an independent mean porosity measurement. The mean porosity oscillates non-monotonically with a decaying amplitude, and the first extremum interval is markedly shorter than the subsequent ones.

Although surfactants are often present in these systems, the role of Marangoni stresses on droplet depinning by an external flow remains unclear. To address this, we develop a lubrication-theory-based model for a thin Newtonian droplet laden with insoluble surfactant on a substrate with Gaussian-shaped defects which are used to account for the effects of surface roughness. The droplet is surrounded by a surfactant-free immiscible Newtonian fluid in a long, narrow rectangular channel, with flow driven by an applied pressure gradient. Using a precursor-film/disjoining-pressure approach for contact-line motion, we derive nonlinear evolution equations for the droplet thickness and interfacial surfactant concentration, which are solved numerically. The pressure gradient transports surfactant from the receding to the advancing contact line, generating a Marangoni flow opposing the pressure-driven flow. This reduces the net shear force on the droplet, leading to depinning at a higher critical pressure gradient. These findings reveal a previously unexamined regime in which interfacial Marangoni stresses, rather than uniform interfacial-tension reduction, govern the critical flow rate. The results provide a mechanistic basis for using surfactant-concentration gradients as a tunable handle to control droplet motion on rough substrates.","PeriodicalId":271,"journal":{"name":"Chemical Engineering Science","volume":"13 1","pages":"125229"},"PeriodicalIF":4.7,"publicationDate":"2026-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149084840","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}

Furthermore, molecular dynamics simulations were conducted to elucidate the microscopic mechanisms responsible for viscosity reduction. The results demonstrated that the nanofluid exhibited outstanding interfacial activity, reducing the IFT from approximately 30 mN/m to 0.5 mN/m and effectively transforming oil-wet rock surfaces to a water-wet state. A stable O/W emulsion was formed, resulting in a viscosity reduction of up to 98% at 80% water cut. Oil-film detachment tests confirmed that the nanofluid completely removed adhered oil films from rock surfaces within 12 h.

MD simulations revealed strong interactions between the nanofluid and asphaltene molecules, which disrupted asphaltene aggregation and inhibited the formation of large aggregates.
