有色金属选矿废水处理研究现状与进展

Research Status and Development of Non-Ferrous Metal Beneficiation Wastewater Treatment

有色金属选矿废水常呈酸性或碱性,含有大量以选矿残留药剂、悬浮物及金属离子为主的污染物。随着矿产资源不断被开发利用,此类废水已成为矿山环境、水体及土壤污染的来源之一,若直接将其用于选矿工艺,各类污染物会损害选矿设备、影响选矿流程、降低精矿品质,故此类废水的综合处理已成为我国乃至世界亟待解决的问题。文章对有色金属选矿废水的处理方法进行总结,阐述了近年有色金属选矿废水处理研究现状,展望其未来的发展方向。

Non-ferrous metal beneficiation wastewater is often acidic or alkaline,and contains a large number of residual reagents,suspended solids and metal ions-based pollutants.With the continuous development and utilization of mineral resources,non-ferrous metal beneficiation wastewater has become a major cause of mine environment,water and soil pollution.The wastewater from mineral processing can not be applied to mineral processing.This was accounted by the fact that all kinds of pollutants can damage mineral processing equipment,affect mineral processing flowsheet and decrease concentrate quality.Therefore,the comprehensive treatment of non-ferrous metal beneficiation wastewater has become an urgent problem that needs to be solved in China and even in the world.This article summarizes the treatment methods of the main pollutants that are generated from non-ferrous metal beneficiation wastewater,expounds the current research status of non-ferrous metal beneficiation wastewater treatment in recent years,looks forward to future development direction of wastewater treatment.
