Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron agglomeration ...

Iron Cake from iron ore fines (-1 mm) without grinding or agglomeration[30] The - 1 mm particles of iron ore were used to make iron cake. The principle of reduction of finer particles (-1 mm) by coal fines being same as that of -10 mm but the reduced product was in the form of iron cake.
Circored® is a two stage fluidized bed process, reducing iron ore fines directly without prior agglomeration, that operates at low reduction temperatures using pure hydrogen as the reducing gas. The hydrogen is produced by means of natural gas reforming, but hydrogen from sources other than a steam reformer, e.g. from water electrolysis, can ...

Iron ores from new ore deposits are either too friable with a low yield of lump (−31.5+6.3 mm) or need to be crushed, ground, and upgraded to achieve the target grade. Therefore, the majority of iron ores currently produced from mines are sinter fines (−8 mm) and concentrates (−2mm even finer).
The plant took iron ore concentrate and produced superior iron ore pellets (which are spheres of high iron content and uniform quality) for blast furnace and direct reduced iron feed. Since then, Grate-Kiln systems have been used for over 50 plants, on both magnetite and hematite ores, with an installed capacity of over 115 million tpy.
