摘要
我国有色冶金废渣年产生量大、综合回收率相对较低、安全处置存在较大环境隐患。首先分类阐述了国内外有色冶金废渣的综合利用技术(湿法浸出、选冶法、火法冶金、微生物浸出和生产建材)、风险防控技术(源头削减与生态恢复、稳定化、固定化)和安全处置技术,随后对上述主要技术的原理、特点、适用范围和优缺点等进行了详细总结分析。最后,对有色冶金废渣综合利用与安全处置技术的发展趋势进行展望。
Nonferrous metallurgical waste slag in China has the characteristics of large annual production,relatively low comprehensive recovery rate and great environmental risks in safe disposal.Comprehensive utilization technologies(hydrometallurgical leaching,metallurgical dressing,pyrometallurgy,bioleaching and building materials production),risk prevention and control technologies(source reduction and ecological restoration,stabilization and immobilization),and safe disposal technologies of nonferrous metallurgical waste slag at home and abroad were elaborated.Principles,characteristics,application scope,advantages and disadvantages of the above technologies were summarized in detail.Based on that,development trend of comprehensive utilization and safety disposal technologies of nonferrous metallurgical waste slag was put forward.
