有色金属矿山选矿废水中硫化物的治理新途径

有色金属选矿厂的选矿废水中硫化物的处理是国内、外矿山废水治理的难题。本研究采用清洁生产审计法,从源头到末端对选矿作业全过程进行调查,将得到的数据、信息分析研究,建立起矿石、工业用水、硫化物的投入和产出平衡,从上述平衡中寻求硫化物时有超标的原因,从而有针对性地提出了分步综合治理硫化物的方案,与传统的一步到位的治理方案比较,具有较大的经济效益和环境效益。本方法亦可以推广到其他矿山应用,这对探索解决矿山废水中硫化物治理这一难题,在理论上和方法上均是一次有益的实践。

ON A NEW WAY FOR TREATMENT OF SULFIDES IN WASTEWATER FROM NONFERROUS METALS CONCENTRATORS

The treatment of sulfides in wastewater from nonferrous metal concentrators is a difficult problem both in China and abroadThe Cleaner Production audit method is used for investigation of whole concentrating processThrough studying the obtained data and information, the input output balances of materials such as ore, water and sulfides were established and the reasons for frequent overplus of sulfides in these balances were found out,thus presenting a comprehensive scheme with stepped treatment of sulfidesCompared with one step treatment,this treating method can obtain greater economical and social benefitsIt is a good experience in theory and method for treating sulfide effluent in nonferrous metals mines
