摘　　要：研究了水杨醛肟、α-安息香肟、邻氨基苯甲酸、8-羟基喹啉和乙二胺五种有机螯合剂对菱锌矿的活化作用,结果表明,五种有机螯合剂都能很好地活化菱锌矿的浮选。通过吸附量的测定、Zn2+离子浓度测定和红外光谱测定分别对乙二胺和8-羟基喹啉活化菱锌矿的机理进行了研究。Activation of five types of organic chelating agents （salicylaldoxime, α- benzoinoxime, anthranilic acid, 8- hydroxyquinoline and ethylenediamine） for smithsonite flotation is researched, the test results show that five types of organic chelating agents all can activate smithsonite flotation commendably. The mechanisms of ethylenediamine and 8 - hydroxyquinoline activating smithsonite are researched by measuring adsorption amount, concentration of Zn^2＋ ion and infrared spectrum.
