The sponge iron is a key raw material for the manufacture of steel. The appropriate percentage of metallization (removal of oxygen) ensures the high quality of the sponge iron. The percentage of metallization is the ratio of metallic iron to the total iron present in the product.

The features and specifications are mentioned below:

Fe Total	88% ± 2%
Fe Metal	76% ± 2%
Metallization	85% ± 2%
Sulphur	0.05 % Max
Phosphur	0.06% Max
Carbon	0.2% Max
Fe Total	88% ± 2%
Size	4 to 20 mm
