Abstract: One of the great triumphs in the field of nano materials and metal by nano technology is the success in developing of nano sized iron powder from iron ore concentrate (blue dust). NMDC has taken an initiative to utilise high-grade blue dust to produce value added product, i.e., nano structure iron powder (NSIP), which can fetch high value. After the up gradation of blue dust by physical method, the samples were leached by acid to produce value added product from blue dust. This was followed by leaching, precipitation, drying, reduction, grinding in argon atmosphere and characterised by SEM, XRD etc to confirm its nano character. This value added product having less than 100 nanometres size has its applications in computer engineering, electronics, instrument making, medicine, catalysis etc. Component made from nano structured materials have attracted large attention due to their high strength, excellent functional properties, better corrosion resistance, reduced sintering temperatures, etc. Paper contains preparation of nano sized particles (less than 100 nanometres) is connected to influence the dimensional effect on their physical, chemical, mechanical and other properties.
