摘要: 针对某选铜尾矿中硫化物残留较多以及重晶石与脉石矿物可浮性接近的特点,试验采用浮选工艺脱除部分易浮硫化物以消除硫化物对重晶石浮选的影响,采用中国地质科学院矿产综合利用研究所自行研制的捕收剂EMLZ-1对重晶石进行浮选回收.最终试验研究确定了较佳的浮选工艺条件,获得了BaSO495.76%、回收率82.21%的重晶石精矿,实现了该尾矿中重晶石的有效回收.

Abstract: In view of copper tailings with many sulfide ores and the similar flotability between barite and gangue minerals,flotation separation in order to eliminate the influence from sulfides was adopted to remove easy-floating sulfide ores,collector(EMLZ-1)researched by Institute of Multipurpose Utilization of Mineral Resources was used to recover barite.Finally,the test determined much better flotation technology conditions and gained barite concentrate with BaSO4 grade of 95.76% at an 82.21% recovery,barite in tailings was recovered efficiently.
