Zinc sulfide concentrates. Determination of zinc. Ion-exchange/EDTA titrimetric method Ingestion-build-47553 BS EN 61286 on coded1 Scope This International Standard specifies an ion exchange EDTA titrimetric method for the determination of the mass fraction of zinc in zinc concentrates. The method is applicable to zinc sulfide concentrates having a mass fraction of zinc in the range from 11 % to 62 %.
