iron ore limestones

Iron Ore

In a blast furnace, iron ore, fuel (often coke) and flux (often limestone) are continuously supplied from the top of the furnace, while blasts of hot air are blown into the lower part of the furnace. At temperatures of approximately 1500°C, silicate and aluminate impurities from the ore and fuel combine with the flux to form a molten slag.
