The study underscored the need to carry out intense research work in this area with a view to blending a high and low grade of iron ores to be used as burden in the blast furnace and Direct Reduced Iron (DRI). The burdens materials in the furnaces with the purpose of producing molten metals. The mechanical properties also reveal the behaviour of the blends through compressive strength results (both green and dry) , Drop Number, Drop Resistance, Green Compression , Dry Compression, Moisture Content, Tumbler Index Value, Abrasion Index, Micro porosity , Drop Number, Drop Resistance, Green Compression, Dry Compression, Moisture Content, Tumbler Index Value, Abrasion Index , Micro porosity and , it is also with a view to determining the blend ratio which gave the optimum indurating compressive strength. And finally the mechanical strength of the fired pellets were determined in order to arrive at the best blend ratio of both ores for the production of molten melts from the furnaces at Ajaokuta and the Direct Reduced Iron (DRI) process at the Delta Steel Company Limited, Aldaja which operates the Midrex process.
