Smelting Reduction Processes
Iron ore fines of up to 8 mm size and coal up to 25 mm size are used. Iron ore fines are pre-heated at approximately 600 °C in a fluidized bed preheater, then preliminarily reduced to 27% at 780 °C in a fluidized bed pre-reduction furnace. The DIOS process has the following characteristics : (1) Iron ore and coal fines can be directly used, (2)

Moving past the Iron Age | MIT Sustainability
Commonly based on a process dating back to the 19th century, iron is extracted from the ore through smelting — heating the ore with blast furnaces until the metal becomes spongy and its chemical components begin to break down. A reducing agent is needed to release the oxygen trapped in the ore, transforming it from its raw form to pure iron.
