Blast Furnace Iron Ore

Iron Ore Distribution across the World

In a blast furnace, fuel (coke), iron ore, and flux (limestone) are continuously supplied through the top of the furnace. A hot blast of air (sometimes with oxygen enrichment) is blown into the lower section. In a blast furnace, iron oxides are converted into liquid iron called "hot metal".

Sintering: A Step Between Mining Iron Ore and Steelmaking

World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.
