| Abstract: | Three new micromolecular depressants, nitrilotrismethenetriphosphonic acid NTP, ethylenebis (ni-trilodimethylene) tetraphosphonic acid EDTP, and hexylenebis (nirtilodimethylene) tetraphosphonic acidHDTP as well as their synthesis method are presented in this paper. The behaviours of NTP, EDTP,HDTP and iminodiacetic acid NDA in pyrite and arsenopyrite flotation were tested. It is illustrated thatthese reagents are selective in pyrite-arsenopyrite mixture separation. The structure-reactivity relation-ship between reagent and mineral is discussed. A reactive pattern of reagent on mineral surface isfounded by quantum chemistry calculation (CNDO/2). |
