history of making sponge iron:

Direct reduced iron - Wikipedia

Producing sponge iron and then working it was the earliest method used to obtain iron in the Middle East, Egypt, and Europe, where it remained in use until at least the 16th century. There is some evidence that the bloomery method was also used in China, but China had developed blast furnaces to obtain pig iron by 500 BCE. The advantage of the bloomery technique is that iron can be obtained at a lower furnace temperature, o

Sponge Iron - an overview ScienceDirect Topics

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 ...

How is Iron Refined from Ore? (with pictures)

Feb 10, 2021  To purify and strengthen iron, materials like coke are mixed in with it to remove oxygen. To coax the oxygen atoms away from the ore requires heat and an alternate atomic partner for the oxygen to bond to. Carbon fills this role nicely, and is readily available in the form of everyday charcoal, or coke, a form of carbon made from coal.
