The shaft furnace is where iron ore is converted to metallic. Iron oxide, in pellet or lump form, is introduced through a proportioning hopper at the top of the shaft furnace. As the iron ore descends through the furnace by gravity flow, it is heated, and the oxygen is removed from the iron ore (reduction) by counterflowing gases that have a

In a conventional MIDREX Plant, the reducing gas needed to feed the shaft furnace in which iron ore is converted to DRI is generated in a reformer. The reformer itself is usually fed with natural gas. The reducing gas produced in the reformer typically comprises 55% hydrogen and 36% carbon monoxide.
