The raw materials used to produce pig iron in a blast furnace are iron ore, coke, sinter, and limestone. Iron ores are mainly iron oxides and include magnetite, hematite, limonite, and many other rocks. The iron content of these ores ranges from 70% down to 20% or less.

CHEMICAL GRADE LIMESTONE | Carmeuse

CHEMICAL GRADE LIMESTONE | Carmeuse

Our chemical grade limestone is used in the ironmaking process to produce the slag, which removes impurities from the iron ore while making liquid pig iron. Limestone is added to iron sinter and pellets to add flux and promote agglomeration in your products. Blast furnaces can add limestone directly to the burden to promote slag formation and protect the refractory.

Pig-Iron Production - Google Sites

Pig-Iron Production - Google Sites

Pig-Iron Production from Microsoft Encarta. The basic materials used for the manufacture of pig iron are iron ore, coke, and limestone. The coke is burned as a fuel to heat the furnace; as it burns, the coke gives off carbon monoxide, which combines with the iron oxides in the ore, reducing them to metallic iron.

Iron Ore Smelting Process - Bright Hub Engineering

Iron Ore Smelting Process - Bright Hub Engineering

The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being disposed of and the molten iron being poured into molds were it solidifies, now being in the form of pig iron. The pig iron is loaded into to an .
