本文从溶液化学理论角度出发,分析讨论了多种捕收剂和黑钨矿表面质点的性质及存在状态以及它们之间的相互作用,找出了捕收剂与黑钨矿表面浮选活性中心的一般关系。捕收剂在酸性介质中,其解离后的离子态和分子态比例为1:1时,黑钨矿表面的活化中心质点为Fe~(3+)及其羟基络合物。捕收剂在中性或碱性介质中,其解离后的离子态和分子态比为1:1时,黑钨矿表面的活化质点为Mn~(2+)及其羟基络合物。提出了离子态-分子态共吸附形式是捕收剂的最佳捕收作用形态的观点。 In this paper, from the point of view of solution chemistry theory, the properties and existing states of the surface aggregates and their interactions among various collectors and wolframite are analyzed and discussed, and the relationship between the collector and the surface flotation active center The general relationship. Collector in acidic medium, the dissociation of ionic and molecular ratio of 1: 1, wolframite activation surface of the center of Fe 3+ and its hydroxyl complexes. Collector in neutral or alkaline medium, the dissociation of the ion and molecular ratio of 1: 1, wolframite activation of the surface of the particle is Mn ~ (2+) and its hydroxyl complexes. It is proposed that the form of ion-molecular co-adsorption is the best mode of collector action.
