第 40 卷第 5 期 中 国 钼 业 Vol . 40 No . 5 2016年 10月 CHINA MOLYBDENUM INDUSTRY Oct 2016 选钼废水性质及回用现状 宛 鹤 ，何廷树 ( 西安建筑科技大学材料与矿资学院，陕西西安710055) 摘 要 :本文以钼的选矿为例，分析了选钼废水的来源、性质及其回用对选钼过程生产的影响 ，介绍了选钼废水的 处理和回用现状;并针对钼矿石的浮选工艺由单一辉钼矿浮选流程变为含钼多金属矿物综合回收流程，引起的选 矿废水复杂化，并对辉钼矿浮选过程产生了不良影响的问题，进一步提出了针对不同性质钼矿石产生的选矿废水 进行深人研究，分析其对选钼效果的影响机制，获得消除或抑制选钼废水回用对选钼过程不良影响的方法或工艺， 以提高选矿废水的回用率，改善选矿废水的回用效果。 关键词:辉钼矿;浮选废水;废水处理和回用 D O I ：10. 13384/j. cnki. cmi. 1006 -2602. 2016. 05. 003 中图分类号:TD954 文献标识码 :A 文章编号： 1006 -2 6 0 2 (2 0 1 6 )0 5 -0011 -0 5 PROPERTIES OF MOLYBDENUM BENEFICIATION WASTEWATER AND ITS REUSE WAN He , HE Ting-shu (College of Materials and Mineral Resources , Xiran University of Architecture and Technology , Xi’an 710055 Shaanx , China ) Abstract ： In the paper , the molybdenum beneficiation was used as an example . The origin , treatment and reuse current situation of molybdenum beneficiation wastewater were introduced . The effects of molybdenum beneficiation wastewater reuse on molybdenite floatation was analyzed . With the focusing on the molybdenum flotation technology from the single molybdenite floatation to the comprehensive utilization of polymetallic molybdenum ore , it is caused that beneficiation wastewater complicated has the adverse effects on molybdenite floatation . Then , the topic that be ­ neficiation wastewater of different properties of molybdenum ore should be studied thoroughly , have been proposed . By analyzing influencing mechanism of beneficiation wastewater complicated on molybdenite floatation , the method or technology on eliminating the its adverse effects on molybdenite floatation , was obtain
