As there can be significant variation in process requirements and sources of iron ore fines, testing is often an essential part of the development of a successful iron ore pelletizing operation. Different sources of iron ore will respond differently to agglomeration, and process requirements will subsequently vary.

DRI: This iron production process directly reduces iron ore in solidstate with the reaction temperature below the melting point of iron. Reducing gases are produced from natural gas (gasbased DRI) or coal (coalbased DRI) called syngas, a mixture of H 2 and CO. Although DRI production is more energy efficient than pig iron production from BF ...
