摘要
随着现代仪器检测技术的不断进步,越来越多的检测手段被引入矿物浮选的机理研究中,其中X射线光电子能谱(XPS)作为一种先进的表面表征分析技术,在揭示矿物浮选过程的微观机制方面发挥着重要作用。综述了XPS分析原理,梳理了XPS的定量与定性研究,总结了XPS在矿物浮选机理研究方面的应用进展。通过XPS可以分析矿物表面元素组成和化学态变化,明确矿物中元素的存在形式,确定浮选药剂的特征原子在矿物表面吸附的化学态,从而可以探究矿物表面活性位点和药剂之间的吸附作用机制。若辅以元素含量及化学态组分含量分析,还可进一步判定药剂吸附能力的强弱。最后,对XPS技术在矿物浮选领域的发展进行了展望,未来将继续完善XPS仪器和理论发展方面的研究。随着XPS与其他多种手段的结合,XPS在矿物浮选机理研究中的应用将更加广泛,为矿产资源的开发利用做出更多贡献。
With the advancement of modern instrumental detection techniques,an increasing number of analytical methods are being applied to investigate the mechanisms of mineral flotation.Among these,X-ray photoelectron spectroscopy(XPS)serves as a powerful surface characterization technique and plays a significant role in elucidating the microscopic mechanisms of the mineral flotation process.In this paper,we systematically summarized the fundamental principles of XPS analysis,reviewed its applications in both qualitative and quantitative studies,and outlined recent progress in utilizing XPS to explore flotation mechanisms.XPS enables the analysis of elemental composition and chemical state changes on mineral surfaces,clarifies the speciation of elements in minerals,and identifies the chemical states of characteristic atoms from flotation reagents adsorbed on mineral surfaces.This information helps reveal the mechanisms of adsorption between active sites on mineral surfaces and reagent molecules.When combined with elemental content and chemical speciation analysis,XPS can further assess the relative adsorption capacity of reagents.Future prospects for XPS technology in the field of mineral flotation are discussed,including ongoing improvements in instrumentation and theoretical developments.As XPS is increasingly integrated with other analytical techniques,its applications in mineral flotation research are expected to expand,thereby contributing more significantly to the development and utilization of mineral resources.
