| 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。

| Abstract: | 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 Zn2+ ion and infrared spectrum. |

| Keywords: | organic chelating agent smithsonite activation adsorption amount infrared spectrum |
