铬渣矿物学性质及其湿法解毒意义

摘要

铬渣是铬盐生产中产生的一种危险工业固体废物,对环境造成了严重危害.湿法解毒是铬渣处理和处置的一种有效方法,但大规模应用依然存在困难.近年来,铬渣的矿物相研究取得了较大进展.总结了铬元素性质和铬渣产生过程,介绍了铬渣矿物相研究成果,总结了铬渣的性质,并探讨了其在湿法解毒中的潜在意义,分析了湿法解毒所存在的困难,提出了相应对策.%Chromite ore processing residue (COPR) is a hazardous solid waste which has brought heavy pollution to the environment. Hydro-based detoxication is an efficient method for COPR disposal and treatment, but there are also many difficulties for large-scale applications.In recent years,great progress has been made in the research for mineralogical phase of COPR.Properties of chromium and the production course of COPR were summarized and research achievements on mineralogical phase were introduced.Furthermore,the mineral characteristics of COPR have been reviewed and their potential meaning in the hydro-based detoxication was also discussed.Problems existed in hydro-based COPR detoxication were analyzed and corresponding solving methods were put forward.
