Abstract

Total reflection X-ray fluorescence (TXRF) has been widely considered as an effective analytical tool for the analysis of a great variety type of polymetallic deposits, because it has many advantages of extremely high sensitivity, high accuracy, minor sample preparation, and the ability of multielement simultaneous analysis. Sample preparation is quite important for TXRF quantitative analysis. Since pretreatment factors, such as sample amount, dispersant type, sample particle size and sample physicochemical properties, are seriously impact the accuracy of results. Based on this reason, investigating an appropriate sample pretreatment strategy is fundamental for accurate assessment of strategic metal elements in polymetallic deposits. This review presents a comprehensive overview of TXRF applications in the field of mineral analysis, including apatite, manganese ore, K-feldspars, granite, copper-nickel sulfide ore, etc. Moreover, the accurate evaluation of TXRF quantitative analysis is detailedly discussed, and the relevant sample preparation methods and preparation factors are also addressed.

摘要

全反射X射线荧光（TXRF）因其具有灵敏度极高、准确度高、样品制备量少、能够检测多种类型多金属矿床的优点，被广泛认为是分析多种类型多金属矿床的有效分析工具。多元素同时分析。样品制备对于TXRF定量分析非常重要。由于样品量、分散剂类型、样品粒径和样品理化性质等预处理因素严重影响结果的准确性。基于此原因，研究合适的样品预处理策略对于准确评估多金属矿床中的战略金属元素至关重要。本综述全面概述了 TXRF 在矿物分析领域的应用，
