摘　　要：鉴定进口矿渣是否为海关监管的固体废物主要根据行业标准《进口矿渣的鉴定通则》(SN/T 3107-2012)。根据本通则进行外观检查、主要物相等特征分析,仅满足对常见矿渣样品的初步筛查。对复杂的"非常规"的矿渣样品,研究表明,通过增加X射线衍射法与X射线荧光光谱法在样品分析中的应用,再深入分析铜矿冶炼过程中的反应机理,对照常见FeOFe2O3-SiO2铜熔炼渣体系相图,同时参考《固体废物属性鉴别案例》,可实现对复杂矿渣样品是否为固体废物的准确和快速鉴定。To identify whether an import mineral slag was a solid waste subject to customs control mainly relied on the industrial standard-＂General rules for identification of import mineral slags＂ （SN/ T 3107-2012）. The characteristic analysis like visual inspection and main phase with the general rules could only meet the requirements for initial screening of common slag samples. For complex ＂uncom- mon＂ slag samples, an accurate and fast method to identificate whether a complex slag sample was a solid waste was achieved by addition of X-ray diffraction and X-ray fluorescence spectrometry in the application of sample analysis, detailed analysis of the reaction mechanisms in the copper smelting process, and reference to the common FeO-Fe2O3-SiO2 copper smelter slag phase diagram and the ＂Solid waste attribute identification case studies＂.
