What three raw materials are used to make pig iron?
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.
What is the purpose of limestone in the blast furnace?
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.
Where does steel come?
Smelting coal, iron ore, and limestone.
What raw materials in the extraction of 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.
Is the core of the earth made of limestone?
No. Earth's core is made of iron and nickel.
What colourcan iron rich limestone be?
yellow
What compound causes limestone rock to be yellow in colour?
Iron oxide can cause yellow to rust colored staining in limestone.
Why can limestone have different textures?
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.
What are the three substances fed into the blast furnace?
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 by heating the coke iron and limestone in a what?
Pig iron is produced when heating * Iron ORE (not iron as the question says!) * Coke * limestone in a Blast Furnace.
What is the mineral colour of limestone?
White.
Which three substances are put into the blast furnace?
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.
What is cement color?
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
What is the difference between fossil rich limestone and chemical limestone?
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.
What three raw materials are used to make pig iron?
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.
What Colour is the dust in central Australia?
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.
Explain how limestone purifies the iron?
When limestone reacts with iron, it removes impurities and forms slag, which is less dense than molten iron and therefore floats over it, allowing it to be tapped off seperatly. It (the slag) is rather useless, but can be used in concrete.
