Iron ores for blast furnace feedstocks. Determination of the reducibility by the rate of reduction index. | Status: Revised, Superseded, Withdrawn

1 Scope This International Standard specifies a method to provide a relative measure for evaluating the extent to and ease with which oxygen can be removed from iron ores, when reduced under conditions resembling those prevailing in the reduction zone of a blast furnace. This International Standard is applicable to lump ores, sinters and hot-bonded pellets.
