摘要

•HEDP used as a depressant in the separation of smithsonite from zinc ions activated quartz (Zn-quartz);•HEDP selectively chelate with active zinc sites on the Zn-quartz surface compared with smithsonite.•HEDP hinders the adsorption of NaOl by desorbing the active sites on the surface of Zn-quartz.
