【摘要】 研究了张家界某镍钼矿1段磨矿细度和粗浮药剂制度,简述了磨矿、浮选流程的确定。粗磨产品2粗3精浮选、再磨的中间精矿2次精选、中矿顺序返回闭路流程处理该矿石,可以获得钼品位为2.21%、回收率为84.53%的钼精矿。用盐酸溶解钼精矿中的磷灰石,可获得钼品位为5.73%、作业回收率为93.34%的钼精矿。更多还原

【Abstract】 A Nickele-Molybdenum Ore in Zhangjiajie was reasearched,focusing on grinding fineness in single-stage grinding and flotation reagent system of roughing.The grinding and flotation flowsheet was introduced.A closed circuit test was carried out by the production of rough grinding floated by two roughing and three cleaning,the intermediate concentrate of regrinding production floated by two cleaning and middlings returned in order.The flotation concentration containing 2.21% of Mo with molybdenum recovery of 84.53% was obtained.Phosphorite contained the flotation concentration was dissolved by hydrochloric acid,then the grade and recovery of Mo concentration could reach to 5.73% and 93.34% respectively.更多还原
