在铁矿X射线荧光分析中,由于矿种、产地和处理方法的不同,矿物组分、化学结合状态及其结晶构造差异较大,致使谱线强度与元素浓度间的关系复杂化,从而可能导致严重的分析误差.这种现象就是所谓的矿物效应和基体影响.文献报导了许多解决办法.本文主要讨论经验系数校正方法在铁精矿、钛铁精矿、赤铁矿、磁铁矿、褐铁矿、烧结矿、球团矿等复杂矿种分析中的应用.
In the X-ray fluorescence analysis of iron ore, due to the differences in mineral species, production area and treatment methods, the mineral components, the chemical combination state and the crystal structure are quite different, which complicates the relationship between the intensity of the line and the elemental concentration and thus may Leading to serious analytical errors.This phenomenon is the so-called mineral effects and matrix effects.Reported a number of solutions in the literature.This paper mainly discusses the empirical coefficient correction method in iron concentrate, ilmenite, hematite, magnetite, Limonite, sinter, pellets and other complex mineral analysis.
