[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,Utilization_of_Microfines_in_Iron_and_St.pdf - Technology,,Technology June 2016 86 Utilization of Microfines in Iron and Steel Making JAGANNATH PAL Principal Scientist National Metallurgical Laboratory A huge quantity of iron ore fines (60 % of ore) is generated during production of lump ore.
