| 摘 要： | 文章根据高岭土中含铁矿物的浮选试验研究,采用胺类与皂化油酸表面活性剂组合作为高岭土中含铁矿物的捕收剂。高岭土中铁的赋存状态表明,采用分段阳离子/阴离子捕收剂组合试剂,当pH=8～10时,十八胺乳化液以静电力吸附形式捕收含铁硅酸盐;当pH=5～7时,皂化油酸和少量十二烷基磺酸钠通过表面活化反应捕收氧化铁矿,使北海高岭土精矿自然白度达到85%～86%,煅烧白度（1 200℃）达到88%～89%。

| Abstract: | Flotation experiment of Fe-beaeing minerals in kaolin is carried out.Amine and and active agent of saponified oleic acid are combined to be used as collector.Occurrence analysis of iron shows that adoption of phased-cationic / anionic collector results in electrostatic adsorption of iron silicate by octadecylamine emulsion at pH=8-10 and capture of iron oxide by surface activation of saponified oleic acid-a small amount of sodium dodecyl sulfate at pH=5-7.Ultimately natural whiteness of the kaolin concentrates increases to 85%-86%,whiteness after calcination（1 200℃）to 88%-89%. |
