In the flotation system of Cu-Fe sulfide minerals, depressants usually preferentially interact with the pyrite surface to render the mineral surface hydrophilic and hinder the adsorption of the collector. This review summarizes the advances in depressants for the flotation separation of Cu-Fe sulfide minerals at low alkalinity. These advances include use of inorganic depressants (oxidants and sulfur-oxygen compounds), natural polysaccharides (starch, dextrin, konjac glucomannan, and galactomannan), modified polymers (carboxymethyl cellulose, polyacrylamide, lignosulfonate, and tricarboxylate sodium starch), organic acids (polyglutamic acid, sodium humate, tannic acid, pyrogallic acid, salicylic acid, and lactic acid), sodium dimethyl dithiocarbamate, and diethylenetriamine. The potential application of specific inorganic and organic depressants in the flotation separation of Cu-Fe sulfide minerals at low alkalinity is reviewed. The advances in the use of organic depressants with respect to the flotation separation of Cu-Fe sulfide minerals are comprehensively detailed. Additionally, the depression performances and mechanisms of different types of organic depressants on mineral surfaces are summarized. Finally, several perspectives on depressants vis-à-vis flotation separation of Cu-Fe sulfide minerals at low alkalinity are proposed.","PeriodicalId":14030,"journal":{"name":"International Journal of Minerals, Metallurgy, and Materials","volume":"22 1","pages":""},"PeriodicalIF":2.232,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139579065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, zinc anodes are subject to unavoidable zinc dendrites, passivation, corrosion, and hydrogen evolution reactions during the charging and discharging of batteries, becoming obstacles to the practical application of ZIBs. Appropriate zinc metal-free anodes provide a higher working potential than metallic zinc anodes, effectively solving the problems of zinc dendrites, hydrogen evolution, and side reactions during the operation of metallic zinc anodes. The improvement in the safety and cycle life of batteries creates conditions for further commercialization of ZIBs. Therefore, this work systematically introduces the research progress of zinc metal-free anodes in “rocking chair” ZIBs. Zinc metal-free anodes are mainly discussed in four categories: transition metal oxides, transition metal sulfides, MXene (two dimensional transition metal carbide) composites, and organic compounds, with discussions on their properties and zinc storage mechanisms. Finally, the outlook for the development of zinc metal-free anodes is proposed. This paper is expected to provide a reference for the further promotion of commercial rechargeable ZIBs.","PeriodicalId":14030,"journal":{"name":"International Journal of Minerals, Metallurgy, and Materials","volume":"20 1","pages":""},"PeriodicalIF":2.232,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139578881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ultimately, the electromagnetic-wave (EMW) absorption property of the CIP@TiO2 composite was improved substantially, the minimum reflection loss reached −46.07 dB, and the effective absorption bandwidth can reach 8 GHz at the composite thickness of 1.5 mm. Moreover, compared with CIP, the oxidation resistance of CIP@TiO2 showed remarkable improvement. The results revealed that the oxidation starting temperature of CIP@TiO2 was about 400°C, whereas the uncoated CIP had an oxidation starting temperature of approximately 250°C.

Stone coal (SC) after vanadium extraction treatment shows potential for secondary utilization in composite preparation.

The combined roasting and acid leaching treatment of raw SC was conducted to understand the effect of vanadium extraction on promoting loading capacity. Results showed that the combined treatment of roasting at 900°C and leaching increased the SC loading of the composite by 6.2% by improving the specific surface area. The loading capacity and thermal conductivity of the composite obviously increased by 127% and 48.19%, respectively, due to the contribution of 3wt% EG. These data were supported by the high load of 66.69% and thermal conductivity of 0.59 W·m−1·K−1 of the designed composite. The obtained composite exhibited a phase change temperature of 52.17°C, melting latent heat of 121.5 J·g−1, and good chemical compatibility.

Machine learning technology provides a new method other than production experience and metallurgical principles in dealing with large amounts of data. The application of machine learning in the steelmaking process has become a research hotspot in recent years. This paper provides an overview of the applications of machine learning in the steelmaking process modeling involving hot metal pretreatment, primary steelmaking, secondary refining, and some other aspects. The three most frequently used machine learning algorithms in steelmaking process modeling are the artificial neural network, support vector machine, and case-based reasoning, demonstrating proportions of 56%, 14%, and 10%, respectively. Collected data in the steelmaking plants are frequently faulty. Thus, data processing, especially data cleaning, is crucially important to the performance of machine learning models. The detection of variable importance can be used to optimize the process parameters and guide production. Machine learning is used in hot metal pretreatment modeling mainly for endpoint S content prediction. The predictions of the endpoints of element compositions and the process parameters are widely investigated in primary steelmaking. Machine learning is used in secondary refining modeling mainly for ladle furnaces, Ruhrstahl–Heraeus, vacuum degassing, argon oxygen decarburization, and vacuum oxygen decarburization processes. Further development of machine learning in the steelmaking process modeling can be realized through additional efforts in the construction of the data platform, the industrial transformation of the research achievements to the practical steelmaking process, and the improvement of the universality of the machine learning models.</div>","PeriodicalId":14030,"journal":{"name":"International Journal of Minerals, Metallurgy, and Materials","volume":"30 11","pages":"2055 - 2075"},"PeriodicalIF":2.232,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12613-023-2646-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134796351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
