CSIR-IMMT/MIN - 14

Fluidized bed reduction Roasting

Advantages / Salient Technical Features
• Direct utilization of low/lean grade iron ore for
production of steel. Presently there is no other
technology available for direct utilization.

Problem being addressed
• There is no technology available, which can directly
utilize the low/lean grade iron ore fines. By this
process, the low/lean grade ore can be utilized for
production of steel.

Environmental Considerations (if any)
• Environment Friendly & utilization of wastes for
creation of wealth

Major Raw Materials to be Utilized
• lean/low grade iron ore fines

IPR Status / Details (India/Abroad)

• Process know how

Application/Uses Commercialization Status
• Can be utilized for magnetizing roasting of low/lean • Not Yet
grade iron ore fines directly through fluidized bed
followed by low intensity magnetic separation (LIMS). Techno-economics
The roasted enriched iron ores are utilized for iron • NA
making through palletization route

Technology Package
Scale of Development
