摘　　要：对河南某萤石矿的矿石进行了可选性工艺研究。在弱酸性介质精选的工艺制度下 ,通过“一粗一扫五精”的单一浮选流程 ,得到的萤石精矿CaF2 品位为 98.2 1% ,回收率为 90 .16% ,精矿中SiO2 含量为 0 .79%。萤石精矿达到国家质量标准 (GB5 690 -85 )一级品。An investigation was made of the flotability and process flowsheet of a certain fluorite ore. A fluorite concentrate grading of 98.21% CaF 2 and assaying of 0.79% SiO 2 and a recovery of 90.16% were obtaibed by processing using a singgle flotation flowsheet consisting of one roughing, one scavenging and five cleanings in weak acidic medium under cleaning conditions. The fluorite concentrate came up to the national quality standards of Class Ⅰproducts.
