    Abstract - (Show below) - (Hide below)

    Describes a solvent extraction/titrimetric method for the determination of the mass fraction of zinc in zinc sulfide concentrates.

    Scope - (Show below) - (Hide below)

    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%.
