Description / Abstract: This document 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 document is applicable to lump ores, sinters and hot-bonded pellets.
