一例进口“铜精矿”的属性分析研究

采用X射线荧光光谱、X射线衍射等技术,结合超景深显微镜、扫描电镜、化学分析等手段,对一例申报为“铜精矿”的样品进行外观形貌、元素组成、物相组成、微观等进行分析。结果表明：样品含有黄铁矿、石英、孔雀石、硅锌矿、滑石等天然矿物,还含有大量的微米级球状氧化锌、玻璃态的钠钙硅铝酸盐、疏松的胶态硅酸盐以及条状、片状的金属铜屑等。样品的特征与天然铜矿浮选得到的铜精矿有显著差别,呈现出天然矿物和多种冶炼加工产物的混合物特征。

Property analysis study of one imported

A sample declared as "copper concentrate" was analyzed by X-ray fluorescence spectroscopy, X-ray diffraction and other techniques, combined with super depth-of-field microscopy and scanning electron microscopy for appearance, elemental composition, physical phase composition and microscopic morphological composition. The results showed that the sample contained natural minerals such as pyrite, quartz, malachite, willemite and talc, as well as a large amount of micron-sized spherical zinc oxide, glassy sodium-calcium-silica-aluminate, loose colloidal silicate and striped and flaky copper metal chips. The characteristics of the sample was significantly different from those of copper concentrates, showing a mixture of natural minerals and a variety of smelting and processing products.
