白云鄂博低品位萤石浮选试验研究
|
摘要
本研究旨在回收某磁选铁矿尾矿中的低品位高碳酸盐型萤石,由于其性质复杂,嵌布粒度细,分选较困难,通过一系列试验,确定以水玻璃、单宁酸和苛性淀粉作为脉石矿物抑制剂,新型高效耐低温捕收剂FX-6Y作为萤石捕收剂,通过1次粗选2次扫选5次精选的工艺流程可以获得CaF_2品位97.66%、SiO_2品位0.23%、CaCO_3品位1.12%、回收率68.37%的精矿。
The purpose of this study is to recover the low-grade and high carbonate fluorite from the tailings of an iron ore in magnetic separation,which is difficult to be separated due to its complex properties and fine disseminated size.Through a series of tests,with water glass,tannic acid and caustic starch as inhibitors for gangue minerals and the new high-performance and low temperature resistance collector FX-6 Yas fluorite collector added in the grinding and flotation respectively,the final concentrate with CaF_2 97.66%,SiO_2 0.23%,CaCO_3 1.12% and recovery rate of CaF_2 68.37%was obtained by aprocess ofone-roughing,two-scavenging and five-cleaning.
