Iron Ore Pellets Technology With Natural Gas India

Sponge Iron Manufacturer India

Sponge Iron also called Direct reduced iron (DRI), is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both
