What colour can iron rich limestone be?
Iron-rich limestone can range in color from rusty red to brown or yellow, depending on the amount of iron present. The iron minerals in the limestone can oxidize and create different hues of color.
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 compound causes limestone rock to be yellow in colour?
Iron oxide can cause yellow to rust colored staining in limestone.
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.
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 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 fossil rich limestone?
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
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.
What minerals can be found in Philippines?
The Philippines is rich in mineral resources such as gold, copper, nickel, chromite, iron, and limestone. These minerals support various industries including mining, construction, and manufacturing.
What is the function of limestone in the furnace?
Limestone is added to the furnace as a flux to help remove impurities from the iron ore during the iron-making process. It reacts with the impurities to form slag, which can be easily removed from the molten iron.
Is the sphinx rusted?
No, the Sphinx is carved from limestone. Iron rusts, limestone doesn't rust. But its limestone is damaged, both by weathering and deliberate acts of man.
