Reduction Kinetics of Fluxed Iron Ore Pellets Made of Coarse Iron Ore …
Waste iron ore fines can be agglomerated by pelletizing to form spherical pellets. Iron ore pellets with or without additives are utilized as an alternate charge material in both conventional and alternative ironmaking processes. Agglomerates in the form of hardened/sintered pellets can partially replace the iron ore lumps in blast furnaces.

Review of Organic Binders for Iron Ore Agglomeration
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 ...

Use of Carbon-based Nanomaterials on the Cold Agglomeration of Iron Ore
Cold agglomerated iron ore mini-pellets (diameter 3–8 mm) with high mechanical strength were prepared. The use of carbon-based nanomaterials (carbon nanotubes and graphite nanoplatelets) as additives to the binder (liquid sodium silicate) promoted the increase of the mechanical strength of the agglomerate to about 285%.

The peculiarity of pellets as agglomerated iron ore raw materials is their tendency to swell during reduction [16, 17]. Swelling occurs at the stage of reduction of wuestite to iron due to the slowing down of the formation of cores of a new phase and the growth of hairline iron crystals. The ISO 4698 standard (Iron ore pellets for blast furnace ...
