利用X射线荧光光谱、X射线衍射光谱、矿相显微镜、扫描电子显微镜和激光粒度分析等多种手段相结合的方法,分析了3个进口有色金属物料的主要成分及其质量分数、物相组成、微观形态和粒度分布,结合外观特征和肉眼可见的杂质,对有色金属物料的产生来源进行分析,根据《固体废物鉴别标准通则》(GB 34330—2017)中的相关条款判断固体废物属性.结果显示,进口的3个有色金属物料分别是电弧炉烟尘、氧化铅矿弃矿和电镀污泥,均属于中国禁止进口的固体废物.这个鉴别方法为进口有色金属物料的固体废物鉴别和监管提供参考.%The main compositions and mass fraction ,phase compositions ,microscopic morphology and particle size distribution of three imported nonferrous metal materials were analyzed by X-ray fluorescence spectrometry , X-ray diffraction technology ,mineral phase microscope ,scanning electron microscope and laser particle size analyzer . Combined with the appearance characteristics and visible impurities ,the origins of the imported nonferrous metal ma-terials were analyzed .According to the relevant identification terms in "Identification standards for solid wastes Gen-eral rules" (GB 34330-2017) ,the solid waste identification conclusion of materials was obtained .The results showed that the three imported nonferrous metal materials were the arc furnace steelmaking dust ,abandoned the oxidation of lead and electroplating sludge .The three imported nonferrous metal materials were all of nonimportation solid wastes . It would provide technical reference for supervising and identifying the solid waste property of imported nonferrous metal materials .
