摘　　要：为合理利用某堆存低品位萤石矿,采用光电-浮选联合流程进行选矿试验研究,光电选矿可以实现矿石中萤石和石英的有效分离,预先抛除大量尾矿,显著降低磨浮工段矿石处理量,使低品位萤石矿的合理利用成为可能。当原矿CaF_(2)品位为17%左右时,采用光电-浮选联合流程,可获得CaF_(2)品位为96.93%的萤石精矿,联合流程CaF_(2)综合回收率为69.80%。In order to make reasonable use of a stacked low-grade fluorite min.the photoelectricity-flotation combined method is used to process in the beneficiation experiments,photoelectric beneficiation can realize the effective separation of fluorite and quartz in the ore.Large amounts of tailings can be removed in advance through photoelectric beneficiation,greatly reduce the ore processing capacity of grinding and flotating section,make the reasonable utility of low-grade fluorite ore possible.When the CaF_(2) grade of raw ore is about 17%,fluorite concentrate with CaF_(2) grade of 96.93%can be obtained through photoelectricity-flotation combined method,and the comprehensive recovery of CaF_(2) is 69.80%.
