process for producing iron from jhama coal and iron ore slime

3A3. Direct Iron Ore Smelting Reduction Process (DIOS)

The Direct Iron Ore Smelting Reduction Process (DIOS) directly uses noncaking coal in a powder or granular form, and iron ore without the use of coke or a sintering process, which are normally required in blast furnace processes. The noncaking coal is directly fed to a smelting reduction furnace, while the iron ore is preliminarily reduced
