In this study, the depression performance of the novel depressant lysine (Lys) on Cu²⁺-activated sphalerite was investigated, and the removal mechanism was elucidated using contact angle tests, surface adsorption analysis, inductively coupled plasma experiments (ICP), zeta potential measurements, FT-IR analysis, and XPS analysis. The micro-flotation experiment findings investigated that, at pH 9.0 and 30.0 mg/L of Lys, the flotation recovery difference between chalcopyrite and sphalerite was 53.16 %. Lys showed different adsorption behaviors on the surfaces of chalcopyrite and sphalerite, as further demonstrated by contact angle and surface adsorption analysis. Moreover, it was discovered that Lys could effectively inhibit the adsorption of sodium butyl xanthate (NaBX) on the sphalerite surface, leading to selective depression. Based on the outcomes of solution chemistry calculations, ICP experiments, and zeta potential measurements, it also could be concluded that Lys accelerated the dissolution of Cu²⁺ on the sphalerite surface and decreased the negative activation, and Lys ions were found to be the essential constituent of the pulp. FT-IR and XPS analyses confirmed that the RCOO^- a hydrophilic group of Lys, had a coordination reaction with the activating copper ions, which made it a high chemisorption capacity on the sphalerite surface. In addition, the amino group (–NH₂) is indirectly involved in the selective depressant mechanism by interacting with Zn²⁺ ions on the sphalerite surface. Therefore, Lys is a novel and effective sphalerite depressant, offering theoretical and scientific guidance for the flotation separation of chalcopyrite and sphalerite.</div></div>","PeriodicalId":18594,"journal":{"name":"Minerals Engineering","volume":"226 ","pages":"Article 109247"},"PeriodicalIF":4.9,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143621197","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}

The force between collector in MOS and graphite is more negative, and its adsorption capacity with graphite particles is stronger than that of traditional collectors.

This study comprehensively studies the rheological and mechanical properties, control methods, and environmental evaluation of high-sulfur CPB. The results indicate that the higher the sulfur content, the higher the shear yield stress and viscosity, and the better the flowability. However, the initial and final setting times are prolonged, and the strength shows a trend of increasing, decreasing, and increasing with the extension of curing time, indicating that the strength attenuation is obvious. By adding different inhibitors to high-sulfur CPB, it was found that naphthalene superplasticizer (FDN) has the best inhibitory effect on strength attenuation. The oxidation of pyrite, which produces SO₄²⁻ and H⁺, is a key cause of strength attenuation. Different inhibitors boost strength mainly by curbing pyrite oxidation. They also enhance compactness by increasing the amounts of hydration products like calcium silicate hydrate (C-S-H), Ettringite (Et), and gypsum to fill pores.

While many studies have focused on modeling continuous variables such as ore and mineral grades with geological domains, the choice of modeling technique depends on the abruptness of the variation across these domains. In cases in which continuous variables display soft fluctuations across domains, a joint simulation approach is advocated. This approach leverages the spatial and local cross-correlations of continuous variables using categorical formations. However, patchy and unstructured categorical simulation outcomes may not accurately represent long-range geological settings. In the context of geometallurgical modeling, continuous variables represent geometallurgical parameters, while categorical variables signify geometallurgical domains, such as mineralization zones. The generation of patchy and unstructured geometallurgical domains remains a challenge when soft boundaries are present. Another challenge in geometallurgical parameter modeling relates to their non-additive nature, rendering block-support simulations through traditional block-kriging or block-simulation techniques ineffective. This study introduces an enhanced geostatistical modeling and co-simulation method aimed at co-simulating copper (Cu), copper oxide (CuO), and the copper oxide ratio (COR), which is strongly correlated with mineralization zones in copper porphyry deposits. The proposed method incorporates soft information from mineralization zones in the form of interpretive geological models and a change of variable technique to address the non-additive nature of the COR, which typically hinders block-support simulations, distinguishing it from CuO and Cu, which are additive variables.
