摘 要: 采用沉淀浮选法对矿山井下酸性废水中重金属离子的去除进行研究。实验结果表明:该方法对铅、铜、锌等离子有很高的去除率,处理后的地下水各项水质指标均达到回用要求和污水综合排放一级标准。铅铜混合浮选精矿中,铅、铜品位分别达到30.2%和16.3%,具有极高的资源回收价值。 In this paper, the removal of heavy metal ions contained in the acidic mine underground wastewater by precipitation flotation were studied. Experimental results show that this process has high removal efficiency of antimony and all the water quality indexes can satisfy the requirements of reuse after treatment, and it can be up to the first grade of wastewater discharge standard, too. The plumber and copper concentrate with a grade of 30. 4 and 16. 3%,it had value of resources reclamation.
