Iron Ore Mining Market Size, Competitive Landscape, Regional Outlook and Driving Factors Analysis - Iron ore mining is the process of extraction of iron mineral from the various mineral deposits and rocks present in mines. The rocks are extracted and undergo the smelting process so that the melted iron can be poured into molds so that various iron-based products are formed.

 · Iron ores are reduced by coke (carbon) in a blast furnace. The process is summarised in the diagram below. Hottest part of the furnace At the bottom of the furnace, adjacent to the hot air blast entry points, the temperature reaches around 1800ºC, and represents the hottest part of the furnace. Ascending vertically, the furnace temperature…

Iron does not exist on the Earth as an element, but rather in the form of its oxides and sulphides in iron ore. They are the starting materials for the technical extraction of pig iron in the blast furnace. The blast furnace operates at 1900 °C in order to smelt iron from iron ore.
