The three raw materials used to make pig iron are iron ore, coke (a type of coal), and limestone. Iron ore is the primary source of iron, coke is used as a fuel and reducing agent, and limestone helps remove impurities from the iron ore during the smelting process.
Smelting coal, iron ore, and limestone.
Limestone is added to the blast furnace as a flux material. It helps to remove impurities in the iron ore by forming a molten slag that floats on top of the molten iron. This slag can then be easily separated from the iron.
The raw materials used in the extraction of iron are iron ore, coke (made from coal), and limestone. Iron ore is the primary source of iron, while coke is used as a reducing agent and fuel, and limestone helps to remove impurities from the iron ore during the smelting process.
No. Earth's core is made of iron and nickel.

Iron oxide can cause yellow to rust colored staining in limestone.
The colours of limestones vary depending on their chemical composition. An iron content to limestone can give a tinge of iron oxide (rust) colour. The exact chemical composition will depend on the origin and geological process resulting that stone.
The three substances fed into the blast furnace are iron ore (in the form of sinter, pellets, or lumps), coke (a form of carbon derived from coal), and limestone (which helps remove impurities from the iron ore and acts as a flux).
Pig iron is produced when heating * Iron ORE (not iron as the question says!) * Coke * limestone in a Blast Furnace.
White.
In a blast furnace, iron ore (Fe2O3), coke (carbon), and limestone (CaCO3) are commonly used. Iron ore is the source of iron, coke acts as a fuel and reduces the iron ore to iron, and limestone helps remove impurities by forming a slag.
fossil rich limestone is made by the earth and is enhance with fossils although the chemical is man made, the two are basically the same.
The colour of cement is Grey.The grey colour is due to the presence of iron oxide.The coloured cement consists of portland cement with 5-10% pigment.White cement - pure limestone + china claychromium oxide - greencobalt - blue

Soils in sub tropical regions are rich in laterite, and contain much aluminum and iron. The oxides or iron give the soils, dust and sand a red cast.
Fossil rich limestone is limestone with various sea creature fossils in it such as shells. It is organic and fine grained. It is sedimentary... Yea that's it :P
