组合捕收剂协同增效机制及其在浮选中的应用进展

Synergistic Mechanism of Mixed Collectors and Its Application in Flotation

组合捕收剂的协同增效对改善单一捕收剂性能缺陷有着重要作用,通过广大研究者针对组合捕收剂的最新研究,详细阐述了组合捕收剂协同增效的具体机制和原理,主要分为共吸附机理、电荷补偿机理、疏水强化机理和捕收剂性质互补机理。针对组合捕收剂在浮选中的不同应用,分类描述了不同种类组合捕收剂在浮选中的最新使用情况。针对组合捕收剂协同增效现有研究的不足,提出建立理论计算与分析表征相结合的捕收剂间协同增效机制研究平台,发展新的分析表征技术,加强捕收剂间促溶、促分散等方面的基础研究,建立对应的构效关系,并使用大数据、机器学习和人工智能,这将对高效组合捕收剂的研究有着重要意义。

The synergistic effect of mixed collectors plays an important role in improving the performance defects of single collectors.Based on the latest research on mixed collectors by a large number of researchers,the specific mechanism and principle of the synergistic effect of mixed collectors are elaborated in detail,which is mainly divided into co-adsorption mechanism,charge compensation mechanism,hydrophobic strengthening mechanism and complementary mechanism of collector properties.According to the application of mixed collectors in flotation,the latest applications of different types of mixed collectors in flotation are introduced.In view of the shortcomings of existing studies on the synergistic effect of mixed collectors,it is suggested that establishing a research platform for synergistic mechanism between collectors by combining theoretical calculation and characterization,developing new characterization technologies,strengthening the basic research on the solubility promotion,dispersion promotion and other aspects between collectors,establishing corresponding structure-activity relationship,and using big data,machine learning and artificial intelligence will be of great significance for the research of efficient mixed collectors.
