yield calculation of iron ore for sponge iron
Sponge Iron Units 18.50 29.60 Total: 53.31 Note: Assuming no scrap is being used. For producing one tonne of crude steel, 1.6 tonnes of iron ore consumption has been assumed. If we add iron ore requirements of RINL of about 5.00MT (3.13 MT x 1.6 tonnes), the total iron ore requirements from non-captive mines work out to 58.31MT or about 60MT.

The Assay Guide to Iron Ore
What is iron ore? Iron ore is a mineral substance that generates metallic iron (Fe) when heated with a reductant. Iron ore generally comprises iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Hematite is widely considered one of the most important iron ores due to its high-grade concentrate of iron …
