[PDF] Utilization of Microfines in Iron and Steel Making

A huge quantity of iron ore fines (60 % of ore) is generated during production of lump ore. Moreover, iron oxide fines are generated in different units of steel plants such as blast furnace, LD converter, mills etc. Coarser sizes of these are used in sinter plant. However in sintering, there is some restriction of using microfines. It is possible to use in pelletization, but pelletization is a

Iron Ore Statistics and Information USGS

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries.
