【摘要】 研究循环水对某复杂矿化矿浮选的影响,同时对利用两种重金属吸附剂减轻循环水不利影响的效果进行试验评价。结果表明,循环水的使用降低了浮铅的选择性。重金属吸附剂的使用可基本恢复浮选选择性至使用新鲜水的水平。更多还原

【Abstract】 The effects of recycled water on the flotation of a complex Pb/Zn ore are investigated.Two types of heavy metal ion(HMI) absorbents are adopted to evaluate them as a means of mitigating the negative effect of recycled water on flotation.It is found that the flotation selectivity of galena against sphalerite is reduced by the use of recycled water.The flotation selectivity is partially restored to the level obtained with fresh water by the use of HMI absorbent.更多还原
