一种新型阳离子捕收剂DCZ浮选性能研究
Flotation Performance of A Ether-Amine Type Cationic Collector DCZ
摘要
Abstract
In view of the characteristics that traditional anionic collector should be used under condition of high temperature,a Ether-Amine type cationic collector was synthesized in laboratory for the flotation of quartz,magnetite and hematite mineral.The adsorption mechanism of DCZ collector on mineral surface was established by Zeta potential measurements,Fourier transform infrared(FT-IR) spectroscopy,in conjunction with the results of mineral microflotation tests.The experiment indicates that DCZ has an excellent collective effect at the temperature of 5℃ to 35℃ and pH range from 2 to 12 for quartz,magnetite and hematite mineral.And it proved that DCZ has great ability to accommodate different temperature and pH value.The recovery of quartz,hematite and magnetite was 99.5％,99.0％,84.0％,respectively in optimal condition,illustrating the collector with better collecting performance for the recoveries of these three minerals in a lower temperature.At the condition of DCZ dosage 13 mg/L,depressant dosage 16 mg/L,temperature 18 ℃ and pH value 8.0,the best separation of quartz and hematite or magnetite was achieved.Furthermore,the results of zeta potential measurement and FT-IR spectroscopy illustrate that hydrogen adsorption may occur between DCZ and quartz DCZ and hematite,and electrostatic adsorption between DCZ and magnetite.关键词
