摘　　要：以某地区停产企业选矿尾渣为研究对象,排除固体废物反应性和急性毒性危险特性,确定固体废物需进行急性腐蚀性、浸出毒性、毒性物质含量危险特性鉴别。在鉴别过程中,毒性物质的选择不同会直接导致固体废物危险特性判定有明显偏差,对此,通过深入分析固体废物来源和不同物质的性质,校正选矿尾渣毒性物质选择,最终判定选矿尾渣为一般工业固体废物。本研究旨在为从事矿山生态修复和固体废物鉴别的技术人员提供可参考性建议。Taking the tailings from a discontinued enterprise in a certain area as the research object,the reactivity and acute toxicity hazards of solid waste were excluded.It was determined that solid waste requires identification of acute corrosiveness,leaching toxicity,and toxic substance content hazards.During the identification process,different choices of toxic substances can directly lead to significant deviations in the determination of hazardous characteristics of solid waste.Through in-depth analysis of the source of solid waste and the properties of different substances,the selection of toxic substances in the tailings of mineral processing is corrected,and it is ultimately determined that the tailings of mineral processing are general industrial solid waste.This study aims to provide reference suggestions for technical personnel engaged in mine ecological restoration and solid waste identification.
