The iron and steel metallurgy industry faces the question of how to replace carbon in iron ore reduction to reduce CO 2 emission in basic industries and achieve the expectation of "double carbon". This study investigates the reduction swelling of individual iron ore pellet under mixed H 2-CO atmospheres and at temperatures of 800–1000 ℃ by in-situ observation.

Iron ore pellets are one type of iron-rich, intermediate product used during primary iron and steel making. During pellet production, fine-grained iron containing minerals are liberated from low-grade ores, concentrated, and agglomerated into round balls that are thermally hardened to form "pellets". Pellets are then transported to Blast ...
