胺类捕收剂对异极矿等4种矿物浮选行为的影响

Effect of Amide Collectors on the Flotation Behavior of Hemimorphite,Quartz,Dolomite and Limonite

考察了不同碳链长度的胺类捕收剂对异极矿、石英、白云石和褐铁矿浮选行为的影响，讨论了胺的碳链长度对捕收异极矿的影响。结果表明，在pH为9-11的条件下，异极矿的浮选回收率最高，胺对异极矿的选择性随着脂肪胺碳链长度的增加而增加，其中，十八胺对异极矿具有较好的捕收能力和选择性。

A series of experimental studies were made on the effect of amide collectors with different length of carbon - chain on flotation behaviors of hemimorphite, quartz, dolomite and limonite. Meanwhile, the effect of the carbon - chain length on collecting ability of amine had been discussed. The resuhs showed that when pH value of solution is between 9 and 11, there was the best recovery of hemimorphite, the selectivity of amine to hemimorphite is increasing with the increase of the carbon- chain length, octadecylamine has better selectivity and collecting ability to hemimorphite.
