Iron ore - Wikipedia
Metallic iron is virtually unknown on the surface of the Earth except as iron-nickel alloys from meteorites and very rare forms of deep mantle xenoliths. Some iron meteorites are thought to have originated from accreted bodies 1,000 km in diameter or larger. The origin of iron can be ultimately traced to formation through nuclear fusion in stars and most of the iron is thought to have originated in dying stars that are large enough to collapse or explode as supernovae. Although iron is the fourth-most abundant element i…Iron Ore - an overview | ScienceDirect Topics,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. This slag, being less dense than the molten iron, floats and can be tapped off.Iron Ore Distribution across the World | PMF IAS,Pig Iron: Meaning and ImpuritiesMetalsIndustries The composition of pig iron varies with the quality of ore and operation of the blast furnace.

Impurity - Wikipedia
The removal of impurities is usually done chemically. For example, in the manufacturing of iron, calcium carbonate is added to the blast furnace to remove silicon dioxide from the iron ore. Zone refining is an economically important method for the purification of semiconductors.
