Iron ores for shaft direct-reduction feedstocks. Determination of the reducibility index, final degree of reduction and degree of metallization. | Status: Revised, Superseded, Withdrawn

1 Scope This International Standard specifies a method to provide a relative measure for evaluating the extent and ease to which oxygen can be removed from iron ores, when reduced under conditions resembling those prevailing in shaft direct-reduction processes. It specifies the determination of the reducibilty, final degree of reduction and degree of metallization. This International Standard is applicable to lump ores and hot-bonded pellets.
