摘      要：The flotation separation of smithsonite from calcite and quartz using a alkyl diamine ether(GE-609)as the collector was investigated through micro-flotation experiments and the real ore flotation *** results show that GE-609exhibits good collecting capability to three minerals without *** presence of sodium sulfide enhances the flotation of smithsonite and calcite while inhibits ***,both sodium silicate and sodium hexametaphosphate exhibit good selective inhibition to *** real ore test results show that a zinc concentrate containing23.51%Zn with the recovery of71.02%is obtained in the closed-circuit *** understand the adsorption of GE-609on smithsonite surface,zeta potential measurement and FTIR analysis were carried out,and the results indicate that the collector GE-609can adsorb on smithsonite surface through both electrostatic adsorption and chemical adsorption,and the presence of sodium sulfide enhances the adsorption of GE-609.
