Abstract

Abstract: Sodium 2， 3dihydroxypropyl dithiocarbonate (SGX)， a small molecule organic depressant， was used to investigate on the selective depression of galena from chalcopyrite in the flotation tests by diethyl dithiocarbamate， and zeta potential and infrared spectrum measurements were performed to study the interaction mechanism between SGX and minerals. The flotation tests of single minerals showed that SGX has slight activation on chalcopyrite and strong depression on galena in the whole pH range. With the increasing of mass concentration of SGX， the recovery of galena decreases rapidly， while that of chalcopyrite has a slight increase. The satisfied separation results of artificially mixed samples showed that the mass fraction and recovery of copper are 2966% and 8523% at 6 of pH value with 19 g/L SGX， respectively. Zeta potential and infrared spectrum measurements indicated that SGX has more strongly adsorption capacity on galena than chalcopyrite.
