摘要
用Ｆ＿（２０３）－ＴＢＰ混合物作捕收剂（Ｆ＿（２０３）３是一种含Ｎ，Ｃ，Ｏ的有机化合物新药；ＴＢＰ是磷酸三丁酯代号），单宁作抑制剂，浮选车河选厂锡石细泥闭路试验结果，可从含锡１．３８％的给矿得到品位为３８．５５％，回收率为９１．１３％的锡精矿。Ｆ＿（２０３）的毒性比现有浮选车河锡石细泥的捕收剂的毒性低；药剂费用也可降低２２％～２３％。
The mixture of F_(203) and TBP as a collector for flotation of cassiterite slime of Chehaoconcentration plant was investigated，using tannin as a depressant．F_(203) is an organic com-pound，which includes N，C，O elements ；TBP is the tributyl phosphate. Experimentsshowed that， when the run in ores contain 1 .38％ Sn，a Sn concentrate assaying 38．55％ canbe obtained with a recovery of 91．13％.The toxicity of F_(203) is lower than ordinary cassterite collector. If F_(203) is used as the col-lector for the flotation of cassiterite slime of Chehao concertration plant,the cost of flotationreagent may be decreased by 22％～23％，
