Coagulation and flocculation study of iron ore fines ...

Reduction of iron ore fines by coal fines in packed and fluidized beds has been studied. The investigation includes study of the kinetic aspects of reduction, carbon and sulfur content of the direct reduced iron (DRI) produced, and metallography of the products.

Direct reduced iron - Wikipedia

Direct-reduced iron (DRI), also called sponge iron, 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.

Investigation on the Kinetics of Iron Ore Fines Reduction ...

Kinetics of Brazilian iron ore fines reduction was investigated in a micro fluidized bed, a newly developed kinetics analyzer for gas-solid reactions, where the effects of external and internal diffusion were significantly reduced by modifying the operation conditions.
