摘要
综述了我国排放尾矿的情况,介绍了目前我国在尾矿的综合利用、尾矿的浓缩与压滤、尾矿回水的循环利用等减排技术及减排设备方面的主要进展,从循环经济角度对选矿厂的减排途径进行了思考,并例举了我国选矿厂在尾矿零排放、尾矿作建筑材料、废水回用、尾矿再选等方面的减排实例,最后对选矿厂减排进行了展望。
The paper reviews the tailing discharge conditions in China, presents the main progress in the discharge reduction technology and equipment including the comprehensive utilization of tailings, thickening and press filtering of tailings and recycling of tailing water, and also considers the ways to reduce the tailing discharge from concentrators from the ,siewpoint of cychc economy. The real cases of the discharge reduction are cited, including the zero-discharge of tailing, tailing use as building material, wastewater recycling, and tailing reconcentration and finally, the discharge reduction of concentrators is prospected.
