浅析有色金属浮选尾矿排放工艺与选矿生产用水重复利用率的关系

随着有色金属采选建设项目的增加,选矿生产的耗水量日渐为公众及管理部门所关注,在整个生产过程中,除精矿粉中会带走精矿重量约10%的水分外,绝大部分排放水是尾矿矿浆经输送至尾矿库澄清后排出的。因此从环境保护及提高水的利用率角度考虑,选矿废水应回用,而尾矿的排放方式又对生产用水回用率有着很大的影响。

Analysis the Relationship between Tailing Emission Technology and Production Water Reusing Rate of Non-ferrous Metals Flotation in EIA

With the increase of Non-ferrous metals flotation projects over these years, the public as well as the government are becoming increasingly concerned about the excessive water consumption in the mineral separation production. During the production process, the most of the production water discharged from the tailings except 10% taken by concentrate. Therefore, in the view to consider on benefit of environmental protection and the utilization of water improved, the mineral dressing wastewater should be reused. And tailing discharge method has great effect on the reuse rater of productive waste water.
