Fuel is 'Coke' an impure form of carbon
Flux is 'Limestone' used to 'soak-up' other unwanted materials in the reduction process.
Also, Don't forget you also need HOT AIR'.
Coke, Limestone and haematite ore are intimately mixed. Then charged into the Blast Furnce. Where a Blast of Hot air blows through the mixture.
The first stage is that limestone thermally decomposes into calcium oxide (lime) and carbon dioxide. Concurrent the coke combines with the hit air to form more carbon dioxide. However, there is an excess of coke, so the carbon dioxide, is reduced to form carbon monoxide.
The second part of the process is that carbon monoxide reacts with the haematite to reduce the haematite to iron, and carbon dioxide.
The lime formed earlier reacts with any impurities present, notably silicon dioxide (sand) to form calcium silicate.
Here are the reaction eq'ns.
CaCO3 ==ht==> CaO + CO2
C + O2 = CO2
2CO2 + 2C(Excess coke) == 4CO
12CO + 4Fe2O3 = 12CO2 + 8Fe
CaO + SiO2(Impurites) = CaSiO3 (Slag).
The slag produced is used to make 'breeze blocks' for building , and for road surfaces.

What is percentage of iron in haematite?
Hematite, which is a common iron ore mineral, is composed of approximately 70% iron.
What is the name of the most common aluminium ore?
The most common aluminum ore is bauxite. It is a sedimentary rock that is rich in aluminum hydroxide minerals.
What metal does haematite make?
Haematite is another name for iron ore. The prefix 'Haem' comes from Classical Greek for iron. Compare with the Latin for iron , which is 'Ferrum' (Fe). Haematite is an oxide of ioron. So by smelting, iron ore was reduced to iron. So the metal in haematite is IRON. Compare with the biological name 'haemaglobin', part of the blood in humans. The 'haem' moiety indicates the 'iron' ion. Or the word ' **Haematuri**a', This is a medical term , for blood in the urine stream.
How many metals does haematite ore contain?
Hematite ore contains one metal, which is iron. Hematite is an iron oxide mineral that is the most important ore of iron.
How is iron usually separated from its ores?
Iron is usually separated from its ores through a process called smelting, which involves heating the ore with a reducing agent such as coke. This process removes the oxygen from the ore, leaving behind the pure iron metal. The impurities in the ore combine with the flux to form a slag that is then removed.
Haematite is an ore of?
Hematite is a mineral made of iron and oxygen. It can be gray, red, or brown.
Is hematite a source of iron?
The main raw material for iron-making is iron ore.There are two iron ore minerals:haematite and magnetite.Actually haematite is an ore where iron is extracted.One can say that haematite is a source if iron.
Is iron ore and lead mined?
Iron ore (haematite) and lead ore (galena) are both both obtained through mining and quarrying.
What is ironore?
Iron ore is the IMPURE mineral rock that contains Haematite (Iron (III) Oxide).
What is percentage of iron in haematite?
Hematite, which is a common iron ore mineral, is composed of approximately 70% iron.
What form of iron is the chief iron ore?
The chief form of iron ore is hematite, which is a mineral form of iron(III) oxide (Fe2O3). Hematite is a common iron ore that is widely used for extracting iron.
Why is iron ore shipped?
To turn iron ore into iron requires a fuel and a flux, frequently coal and limestone. It usually costs less money to ship the iron ore than it does the coal and the limestone, especially if those two are close together. So shipping costs are the reason.
What metals are found in Ukraine?
The Ukraine has huge deposits of coal and iron ore. Therefore, the main minerals in Ukraine are carbon and haematite.
Iron ore is made of what mineral?
Iron ore is typically an oxide of iron. Haematite is very commonly mined this is a mineral form of Fe2O3. Magnetite has been mined , this is a form of Fe3O4.
What are the uses of ORe?
Ore, as in rocks which contain sufficient metal to extract and it is economical to do so. Ores include bauxite, a copper ore. Ores can be used to extract precious metals which in turn can be used for electrical wiring, in the case of copper or as a catalyst, in the case of Haematite, Iron ore (the haber process).
What is the best quality of iron ore?
The best quality of iron ore is typically high-grade iron ore, which contains a high percentage of iron content and few impurities. High-grade iron ore is more valuable and in demand in the steelmaking industry because it requires less processing to extract the iron.
What is the name of the most common aluminium ore?
The most common aluminum ore is bauxite. It is a sedimentary rock that is rich in aluminum hydroxide minerals.
