铜精矿及其冶炼过程中相关固体废物的综合表征

摘要

采用X射线荧光光谱(XRF)、红外光谱(IR)以及偏光显微(PM)分析联用技术对进口铜精矿及其冶炼过程中产生的相关固体废物冰铜渣和阳极炉渣进行鉴别.XRF对元素组成及其大致含量进行表征,IR对其中的脉石矿物物相进行识别,PM对其中的非脉石矿物物相进行识别.3种表征手段的联用,可以对其中的物相进行全面的识别.结果表明,铜精矿、冰铜渣和阳极炉渣的的物相组成基本无交叉.通过物相分析可以准确判定其物相归属,从而实现对铜精矿及其冶炼过程中产生的相关固体废物进行有效鉴别.%X-ray fluorescence spectrometry (XRF), infrared spectroscopy (IR) and polarizing microscopy (PM) were applied to identify copper concentrates and solid wastes of matte residue and anode furnace slag produced in the copper smelting process.XRF, IR and PM were used to characterize elemental composition, gangue minerals, and non-gangue minerals, respectively.With the three methods combined, the phases could be indentified.The results showed that there was no overlapping in phase composition of copper concentrate, matte residue and anode furnace slag, and phase retrieval could be accurately determined through phase analysis, so that copper concentrate and solid waste produced in smelting process could be identified effectively.
