摘　　要：某萤石矿石中萤石和重晶石含量高,但矿物可浮性相近,分离难度较大。采用优先浮选工艺,糊精为主要抑制剂,获得了较好的分离指标。闭路试验获得精矿品位96 28%,回收率64 25%的分选指标。The ore is high in both fluorite has high content of both fluorite and barite,of that the floatability are similar and hardly to be separated.Using sequential selective flotation process and adding dextrin as main depressant obtain good separation result.In closed circuit test,the concentrate is 96.28% and the recovery is 64.25%.
