摘　　要：研究了有机抑制剂DMPS对脆硫锑铅矿和磁黄铁矿的抑制作用。结果表明,DMPS对磁黄铁矿有很好的抑制作用,对脆硫锑铅矿几乎无抑制作用。DMPS分子结构中含有—SH,—SO3等多种官能团,黄药和DMPS之间存在竞争吸附的关系,由于DMPS携带亲水基团,使得磁黄铁矿表面更易亲水,因而受到抑制。The effects of organic depressant DMPS on jamesonite and pyrrhotite have been studied. Results show that DMPS has a good depression on pyrrhotite, but hardly has any depression on Jamesonite. There＇ re many kinds of function group such as--SH and --SO3 in the molecular structure of DMPS, Xanthate and DMPS will compete to absorb sulfide minerals in such process. DMPS carries a number of hydrophilic functions groups so as to make the surface of pyrrhotite more hydrophilic which results in the depression.
