摘要
福建某铅锌尾矿中CaF_2含量为28.36%,为有效回收该尾矿中的萤石,对其进行选矿试验研究。通过采用一次粗选、三次精选、一次扫选的闭路浮选回收方案能够有效回收该铅锌尾矿中的萤石,萤石精矿品位达到95.11%、回收率达到90.75%。
The content of the fluorite in a lead-zinc tailings in Fujian was 28.36% and in order to recover the fluorite, mineral processing experimental research was conducted. By using the process of one roughing-three cleanings-one scavenging closed-circuit experiment , the fluorite was effectively recycled from the lead-zinc with CaF2 grade could be 95.11% and the CaF2 recovery rate reached 90. 75%.
