摘要
物理筛分、化学提取、物理化学联合应用等3种典型异位淋洗修复工艺由采矿与选矿工业发展而来。该文阐述了物理筛分、化学提取、物理化学联合工艺的应用原理,总结了物理化学联合工艺的基本流程路线及业内应用情况,分析了上述工艺的适用条件和特性,并提出了几点建议,为异位淋洗技术研究及工艺筛选提供参考。
Three typical ex-situ leaching remediation processes,including physical screening,chemical extraction,and combined application of physical chemistry,were developed from the mining and mineral processing industries.This article elaborates the application principles,applicable conditions,and characteristics of the physical screening,chemical extraction,and physical and chemical combined processes in detail,and focuses on the basic process routes and industry applications of the physical and chemical combined processes.Finally,combined with the intro⁃duction of the application characteristics of the above process,a summary and suggestion are made to provide guid⁃ance and reference for the research of ectopic leaching technology and process screening.
