Directreduction (DR) is defined as any process in which metallicironis produced by the reduction ofironoreat temperatures below theironmelting point. The product of a DR process is calleddirectreducediron(DRI). The major consumers of DRI are the smaller steel mills whichuseDRI to dilute the residual elements present in the steel ...

Althoughironoreconcentrates are generally higher inirongradeand contain lower impurities, the finer size distribution of concentrates limits their usage inironoresintering. Therefore, pelletizing is needed to produce fired pellets from concentrates as burden materials for blast furnaces anddirectreduction processes.

Ironoreis a mineral substance which, when heated in the presence of a reductant, will yield metalliciron(Fe). It almost always consists ofironoxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3).Ironoreis the source of primaryironfor the world'sironand steel industries.
