DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H ...

Sponge 'iron process might well be scaled up to a commercial operation, a full-scale test was car-ried out in a production kiln of 4.6 m diameter and 110 m length, which had been modified to suit the conditions encountered in processing rich iron ores. This test furnished proof that the test results are reproducible on a production scale.
