    Iron ore fluxed pellets and their physical properties

    Jun 01, 1985 This is because, as stated before, the cementing action of bentonite improved the resistance of pellets to breakage- This is particularly noticeable in the case of limestone pellets as well as fluxed iron ore pellets. As limestone particles and pellets are weaker than those of iron ore, increasing the amount of limestone in the pellets from 10 to 20% led to a slight decrease in the crushing strength of fluxed pelletsFigure 7 shows this trend more clearly when the material was pelletized

    Jan 01, 2020 The proportion of additive plays comparatively important role in a pelletization process starting from green pellet to fired pellet and then up to pellet reduction. The iron ore fines (Fe: 64% and LOI: 2.86%), anthracite coal, bentonite and limestone are taken as the pellet feed material. The aim of the present work is to investigate the effect of additives (bentonite, limestone and anthracite coal)

    Jul 11, 2018 The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing
