The carbon monoxide REDUCES the iron oxide in the ore into molten iron which flows to the bottom of the furnace. Limestone is added to remove acidic impurities forming a molten slag which floats on top of the iron. The carbon monoxide combines with oxygen from the iron ore to produce carbon dioxide. This is called OXIDATION.

Oct 15 2022Which of the following is used for extraction of iron Iron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as haematite contain iron(III) oxide Fe 2 O 3. The oxygen must be removed from the iron(III) oxide in order to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions.
Which compound is obtained as slag in extraction of iron in blast furnace In this part Haematite (Fe 2 O 3) and Magnetite (Fe 3 O 4) are reduced to Ferrous Oxide (FeO). The limestone also decomposes to CaO which removes the silicate impurity of the ore in the form of Slag. It can be easily separated out of molten iron.
Best Answer. Copy. Extraction. Extraction of Iron is done in many steps like oxidation combustion fusion reduction etc. During extraction cast iron is formed first which is then converted to

This concentrated ore is mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs. The extraction of iron from its ore is a long and subdued process that helps in separating the useful components from the waste materials such as slag.
Mar 29 2022During extraction of iron slag produced is The calcium oxide then reacts with silica (sand) impurities in the haematite to produce slag which is calcium silicate . This is separated from the iron and used to make road surfaces.
The combustion of iron ore with other materials in the blast furnace produces molten pig iron which is then converted to steel. Blowing oxygen forces impurities (oxides silicates phosphates etc.) to react with flux to form slag or escape through the top of the furnace as fumes.
Answer (1 of 4) Slag is less dense than iron so it floats on the surface. In a blast furnace the hot metal comes out of the tap hole in the side of the furnace and goes down a trough or runner. A refractory coated skimming blade skims the surface of the hot metal directing the lighter slag off
There are four main types of iron ore deposit massive hematite which is the most commonly mined magnetite titanomagnetite and pisolitic ironstone. These ores vary in colour from dark grey bright yellow or deep purple to rusty red. Iron is responsible for the red colour in many of our rocks and the deep red sands of the Australian deserts.
The extraction of iron occurs in the blast furnace. The term "blast" refers to the supply of combustion air above atmospheric pressure.
