萤石矿降硅浮选工艺研究

Study on Reducing the Silica in Fluorite by Flotation Technology

研究了某萤石矿生产优质低硅萤石精矿的浮选药剂和工艺流程。通过采用一次粗选、一次扫选、五次精选、弱酸性介质精选的浮选工艺 ,获得含CaF2 99.0 8%、SiO2 0 .6 2 %、回收率为 86 5 5

The flotation reagent and technological flowsheet of producing high quality low silica fluorite concentrate a fluorite mine of a were stuided.The application of the technology of flotation in weak acidic medium,which consists of one roughing,one scavenging and five cleanings has abtained a low silica fluorite concentrate with a CaF 2 content of 99.08%,SiO 2 content of 0.62% and a recovery of 86.55%.
