Pellet porosity is significant to the diffusion of oxygen during the oxidation and reducing gases through fired pellets and therefore critical to both physical and metallurgical quality.enPellet porosityMercury porosimetryPore characteristicsIron oreGreen ballsFired pelletsNatural Resources Research InstituteUniversity of Minnesota DuluthTechnical Report
