铁矿石阳离子反浮选是铁精矿精选最有前途的方法之一。这种方法在苏联各选矿企业中难以投入使用,在很大程度上是因为缺少有效而且毒性小的阳离子捕收剂。目前已研制了大量的阳离子表面活性剂,然而,在选择矿石浮选捕收剂时,主要用试验方法。为研究阳离子表面活性剂对石英和其他 Iron ore cation anti-flotation is one of the most promising methods of concentrating iron concentrates. This method is difficult to put into operation in the various mineral processing enterprises in the Soviet Union, due in large part to the lack of effective and less toxic cationic collectors. At present, a large amount of cationic surfactants have been developed. However, in the selection of ore flotation collectors, the test methods are mainly used. For the study of cationic surfactants on quartz and others
