| 摘 要： | 某超大型复杂铀多金属矿具有有价元素含量低、目的矿物种类多而含量少的特点,为减少选别工作量,降低企业生产成本,有必要对该矿石进行预抛尾。从工艺矿物学角度探讨了预抛尾的可行性,最后建议在-2mm破碎细度下采用螺旋溜槽重选进行预抛尾,使有用矿物得到有效富集,并最终取得良好的选矿指标。

| Abstract: | Due to a great variety of recoverable minerals in the low-grade uranium polymetallic ore, it is necessary to pre-discard the tailings in order to reduce the separation workload and reduce the production cost of the enterprise. In this paper, the feasibility of pre-discarding tailings is discussed based on the process mineralogy study. Finally, gravity separation with spiral chute is suggested to pre-discard tailings to enrich useful minerals and obtain good dressing index under the grinding fineness of-2mm. |
