The metallic iron in this process is produced by the reduction of iron oxide below the fusion temperature of iron ore (1535 deg C) by utilizing carbonaceous material present in the non-coking coal. As the iron ore is in direct contact with the reducing agent throughout the reduction process, it is often termed as direct reduced iron (DRI).
Iron Ore is a basic type of ore which is abundant in the world. It is smelted into Iron Ingots or alloyed into Steel Ingots for further processing.

The outright S&P Global Platts Turkey import HMS 1/2 (80:20) scrap …
Haematite, an ore of iron, first concentrated and then calcined. The calcined ore is then heated in a blast furnace in presence of coke the limestone and at the same time a blast of hot air (pre heated to 1000 K ) is introduced into the furnace through tuyeres.
These costs must be controlled in a competitive iron and steel market. Careful consideration at all steps highlighted in this series of articles can lead to significant improvement in yield, and thus a major reduction in operating cost. *V ratio is defined as % CaO / % SiO2 in weight percentage – also called B ratio or B2 ratio.
