Zinc sulfide concentrates. Determination of zinc. Solvent extraction and EDTA titrimetric method Ingestion-build-109673 Rationalization arising from the publication1 Scope This International Standard specifies a solvent extraction titrimetric method for the determination of the mass fraction of zinc in zinc sulfide concentrates. The method is applicable to zinc sulfide concentrates having a mass fraction of zinc in the range from 11 % to 62 %.
