某铜铅锌硫化矿浮选废水特性研究

Research on the Floatation Wastewater's Property of Copper-lead-zinc Minerals

研究某铜铅锌硫化矿的浮选废水,通过将其多次回用到浮选流程中,得到各种废水指标的变化规律,包括悬浮物含量、COD值及重金属离子的浓度,并从废水对浮选过程及产品指标影响规律的角度对废水作出评价,以铜精矿中的铅和锌的含量作为评判标准,从而为浮选废水的处理和回用提供了依据。

The research object is floatation wastewater,through reusing it in the floatation for many times,the changing regularity of the wastewater index were obtained,including SS,COD,and the metal iron concentration.The evaluation of wastewater had been also made from the point of effect to floatation process and its products,taking content of lead and zinc in copper concentrate as criteria,which offered basis for treatment and reuse of wastewater.
