【摘要】：针对传统阴离子捕收剂需对矿浆加温才能使用的弊端,研制了一种醚胺类阳离子捕收剂DCZ。以石英、赤铁矿、磁铁矿为试样对捕收剂DCZ的浮选性能进行了试验研究,并借助动电位检测及红外光谱检测等检测手段对捕收剂DCZ与三种单矿物的作用机理进行了探讨。浮选研究结果表明:以DCZ为捕收剂,在浮选温度5℃到35℃、pH值为2~12范围内,DCZ对温度与pH值的适应力极强,最佳条件下石英、赤铁矿及磁铁矿回收率分别为99.5%,99.0%,84.0%,且在淀粉作抑制剂,DCZ用量13 mg/L,抑制剂用量16 mg/L,温度为18℃,pH值为8.0的条件下,捕收剂DCZ对石英与赤铁矿及磁铁矿之间的分选效果最好,能够实现各试验矿样间的有效分选;结合Zeta电位检测及红外光谱检测结果表明,捕收剂DCZ与石英及赤铁矿发生了氢键吸附,与磁铁矿发生了静电吸附。

The flotation properties of collector DCZ were studied by using quartz, hematite and magnetite as samples, and the mechanism of action of collector DCZ with three single minerals was discussed by means of potentiodynamic detection and infrared spectroscopy. The results of flotation study show that when DCZ is used as collector, the recovery of quartz, hematite and magnetite is 99.5 in the range of flotation temperature from 5 鈩，
