Abstract

For high-efficiency utilization of fluorite ore in Kengkou Suichang,experimental research on main chemical components,mineral composition and mineral flotation of this ore was carried on.The results show that the ore samples belong to low-grade monosilicate fluorite and the main gangue mineral is quartz and then feldspar,sericite,calcite and kaolinite.When The closed-circuit technical flowsheet of coarse concentrate regrinding and recleaning was adoped by using sodium carbonate and water glass as regulator and KY-108 as collector,the high-grade fluorite concentrate could be obtained.The grade and recovery of CaF2 could reach 97.59% and 97.03% respectively and the content of SiO2 and CaO was less than 1.5%.
