between iron ore and carbon is very effective for reduction17 They produced carbon infiltrated iron ore from precalcined natural goethite ore and pyrolyzed biomass tar and reduced it under an inert atmosphere17 As a result the ore was reduced at lower temperature compared with the mixture of μm sized Fe 3 O 4 reagent and carbon black or coke32 These test methods are intended as referee methods for the determination of iron in iron or It is assumed that all who use these test methods will be trained analysts capable of performing common laboratory procedures skillfully and safely
