An integrated approach combining micro-flotation tests, interfacial characterization (contact angle and AFM tests) and multi-scale spectroscopic measurements (FT-IR、XPS analysis and DFT calculations) was used to reveal the selective depression mechanism of KG. Micro-flotation performance metrics demonstrated that 10 mg/L KG dosage induced a remarkable floatability divergence, sustaining 89.7 % chalcopyrite recovery while depressing sphalerite to 22.5 %. Rheological tests reveal that the viscosity of sphalerite pulp decreased with increasing shear rate, and the shear force exhibited a nonlinear relationship with shear rate in the presence of KG. Conversely, chalcopyrite pulp maintains near constant viscosity and shear force across varying shear rate. Contact angle tests and AFM analyses revealed that KG addition increased the surface roughness of sphalerite, notably reduced the contact angle, and hindered the subsequent adsorption of Sodium butyl xanthate (NaBX). FT-IR and XPS analyses showed that KG exhibited stronger adsorption on sphalerite than on chalcopyrite, achieving selective depression through the synergistic effect of surface coordination bonds and hydrogen bonds, thereby enabling effective separation of chalcopyrite and sphalerite. Additionally, DFT calculations quantified the difference in adsorption energies of KG on chalcopyrite and sphalerite surfaces. In conclusion, this study confirms that KG is a highly selective green depressant. More importantly, it reveals a novel pathway by KG molecules synergistically modulate the mineral interfaces through hydrophilicity and HSAB theory, thus elucidating the critical role of rheological behavior in the depression process. This work provides a theoretical foundation for developing polysaccharide based flotation reagents and promotes the environmentally friendly upgrading of high efficiency separation technology for copper and zinc resources.</div></div>","PeriodicalId":278,"journal":{"name":"Colloids and Surfaces A: Physicochemical and Engineering Aspects","volume":"728 ","pages":"Article 138553"},"PeriodicalIF":5.4,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145218491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this discrepancy, montmorillonite (Mt), kaolinite (Kt), and illite (Ilt) of different sizes were prepared by gradient centrifugation, freeze–thaw, and/or intercalation protocols and subsequently modified via hydroxyaluminum (HyA) and hydroxyaluminosilicate (HAS) oligocations to simulate their natural states and interactions with W(VI) in soil. For all three clay minerals, the smaller particles possessed higher HyA or HAS contents. Additionally, Mt showed the larger loading amounts for two oligocations compared to Kt and Ilt. HyA or HAS loading significantly increased W(VI) uptake, negligibly influenced the adsorption kinetics, and improved the pH resistance. At low concentrations, the clay minerals loaded by HAS showed greater adsorption amounts of W(VI) than those loaded by HyA. The adsorption of W(VI) on unmodified Kt and HyA- or HAS-loaded clay minerals were increased by increasing ionic strength, suggesting the complexation mechanism. HyA-loaded small Kt and Mt induced the polymerization of monomeric tungstate on their surfaces, corresponding to an open-chain and a proximal polymerization models, respectively. Release of the polymerized W(VI) was related to the clay mineral type and W(VI) concentration.

However, the low-pressure environment at high altitudes significantly reduced dissolved oxygen (DO) content in pulp (conventional low-altitude DO=8.2 mg/L), thereby altering the redox behavior at sulfide mineral interfaces and adversely affecting the flotation separation of chalcopyrite and pyrite. The study revealed that under a pH of 12.0, the DO content in high-altitude areas (4600 m, DO = 4.0 mg/L) inhibited the oxidative corrosion of pyrite, leading to a sharp decrease in calcium ion (Ca²⁺) adsorption (from 1.5 ×10⁻⁵ to 0.4 ×10⁻⁵ mol/g), thereby increasing the difficulty of its inhibition. Sodium hypochlorite exhibits stronger oxidizing capacity than oxygen, disrupting the surface structure of pyrite, exposing more hydroxylated iron and sulfate species. The enhanced Ca²⁺ adsorption capacity (0.7 ×10⁻⁵ mol/g) and reduced xanthate adsorption (from 2.9 ×10⁻⁷ to 2.6 ×10⁻⁷ mol/g) enhanced its inhibitory effect. By employing NaClO-enhanced oxidation and extended flotation time, the Cu grade of the concentrate from production samples in high-altitude areas increased from 18.86 % to 20.83 %, demonstrating improved separation efficiency.

Nevertheless, to date, most studies on its oil-water interfacial properties have focused on the impact of reservoir environments, while research on the interfacial self-assembly of its mixed systems remains relatively few. In this paper, the interfacial self-assembly behavior of linear alkyl betaine (ASB) and internal olefin sulfonates (IOS-C₁₈, IOS-C₂₄) with total carbon number of branched alkyl of 18 and 24 was investigated using the spinning drop method, and the influence of oil phase properties was further investigated. The experimental results indicate that the branched structure of the hydrophobic group in internal olefin sulfonate exhibits a certain self-regulating capacity, which not only has a certain interfacial activity, but also can make up for the adsorption void of betaine molecules on the oil-water interface. Under optimal hydrophilic-lipophilic balance (HLB), the composite system can reduce the n-decane-water interfacial tension (IFT) to an ultra-low level. Meanwhile, the properties of the oil phase represent a key factor affecting the composition and structure of mixed adsorption film. The fractions in Shengli crude oil compete with surfactant molecules for adsorption; consequently, the oil-water IFT is high. In contrast, the small-molecule active components in Changqing crude oil can be mixed with the system, exhibiting low branching degree, and the IFT is low.
