Abstract
A continuous process provides direct reduction of iron ore in a solid state. Briquettes of iron ore fragments and biomass are transported through a preheating chamber and preheated to a temperature of at least 400° C. The preheated briquettes are transported through a heating/reduction chamber that has an anoxic environment, and iron ore and biomass in the briquettes are exposed to electromagnetic energy in the form of microwave energy under anoxic conditions. Microwave energy generates heat within iron ore, and biomass acts as a reductant and reduces iron ore in a solid state, as the briquettes move through the heating/reduction chamber.
