yield calculation of iron ore for sponge iron

Iron Ore and Coal Manufacturer | Tata Sponge Iron Limited ...

During sponge iron manufacturing, iron ore is reduced in solid state. Unlike the conventional steel melting processes, the gangue content of iron ore cannot be separated as a slag. Hence, it becomes essential to select an ore with high iron content and a low gangue content, to optimise yield during steel making.

Direct Reduced Iron (DRI) - Cargo Handbook - the world's ...

Direct-reduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. The reducing gas is a mixture majority of hydrogen (H2) and carbon monoxide (CO) which acts as reducing agent.

Direct reduction of iron (DRI) – ‘Sponge iron’

Sponge iron is the product created when iron ore is reduced to metallic iron, in the presence of coal, at temperatures below the melting point of iron. The external shape of the ore is retained with 30% reduction in weight due to oxide reduction resulting in change in true density from 4.4 gm/cc to 7.8 gm/cc in this product.
