在硫化矿的浮选实践中,常采用黄原酸盐、硫代及二硫代磷酸盐、硫代氨基甲酸盐及其它一些药剂作为捕收剂,这些药剂的成盐基团中都含有作电子的活性原子、S、N、O,一般说来,这些原子在药剂分子结构中的一定的结合确定了浮选时药剂对矿物的选择作用。但成盐基团中不含S、N、O也能起到同样作用,例如 In the flotation practice of sulphide ore, xanthate, thio and dithiophosphates, thiocarbamates and other agents are often used as collectors, all of which contain salt-forming groups Electron active atoms, S, N, O, in general, the combination of these atoms in the molecular structure of the drug determines the choice of minerals for flotation. However, the salt-forming group does not contain S, N, O can play the same role, for example
