苯乙烯磷酸是锡矿物有效螯合捕收剂。为了使苯乙烯磷酸在矿物浮选方面得到广泛应用,以及进一步开拓苯乙烯磷酸类的新的螯合捕收剂,我们对苯乙烯磷酸进行了化学修饰,在其分子上引入含有氨基、羧基或酰胺键等配位基团。为此目的。我们先合成了三种新的苯乙烯磷酸螯合捕收剂,并探索了这四种螯合捕收剂对Sn~(2+)、Cd~(2+)、Pb~(2+)、Mn~(2+)、Fe~(3+)和Bi~(3+)等六种金属的捕收能力。 Styryl phosphate is an effective chelate collector of tin minerals. In order to make styrene phosphate widely used in mineral flotation, as well as to further develop new chelating collectors of styrene phosphoric acid, we modified the styrene phosphoric acid into molecules containing amino, carboxyl or Amide bond and other coordination groups. For this purpose. We first synthesized three new styrene phosphate chelating collectors, and explored the effects of these four chelating collectors on Sn2 +, Cd2 +, Pb2 +, Pb2 + Mn ~ (2 +), Fe ~ (3+) and Bi ~ (3+).
