| 基于已完成的112例进口含金属物料的固体废物鉴别实践，系统地介绍了进口含金属物料的申报品名及各品名所占比例，种类及各种类的特征、固体废物鉴别关键方法和每种鉴别结果所占比例，其中申报品名主要为矿石（砂），所占比例为51.8%；鉴别结果主要为冶炼渣，所占比例为37.5%。提出对于进口的含金属物料，通过测量主要成分和含量、最主要金属元素及典型重金属元素的含量、物相组成、矿相组成，对于极细的粉末等特殊物料，还需要粒度分析等辅助试验，确定其产生来源。如果确定属于金属冶炼过程中产生的副产物、污染控制设施或环境治理过程中产生的物料、含金属废料简单加工处理产物、矿物采选过程中产生的废弃物，那么鉴别物料属于固体废物。 |

| Based on 112 cases of solid waste identification for import metal containing materials，this paper systematically introduced the declaration names，types and proportion of these import metal containing materials.The characteristics of different type of metal containing materials as well as the critical methods for identifying their solid waste properties were discussed.Results showed that the main declaration name was ore，which accounted for 51.8% of total imported metal containing materials.The identification results showed that 37.5% of import metal containing material was smelting slag.This paper would provide technical references for supervising and identifying the solid waste property of import metal containing materials，which had great significance for preventing the import of smelting slag，mud，dust and other metal containing solid waste. |
