It s within the furnace that extraction of iron occurs. The extraction of iron from its ore could also be an extended and subdued process that helps in separating the useful components from the waste materials like slag. In the smelting step the haematite ore is mixed with coke and limestone approximately within the ratio of 8 4 1 .
Iron ore Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey bright yellow or deep purple to rusty red. The iron is usually found in the form of magnetite hematite goethite limonite or siderite.

The main ores are i) Haematite (Fe2O3) ii) Magnetite (Fe3O4) iii) Iron Pyrites (FeS2) o The main iron ore is Haematite (iron (III) oxide Fe2O3). o The iron ore contains impurities mainly silica (silicon dioxide). o Since iron is below carbon in the reactivity series iron in the ore is reduced to iron metal by heating with carbon (coke). 7.
Solution During the extraction of iron from haematite ore limestone acts as a flux. Limestone decomposes froming CaO which reacts with silica forming slag. Why is limestone added to the blast furnace during iron extraction Limestone is also used to remove impurities from the blast furnace when making iron. The impurities are mostly silicon

The Haematite reacts with Carbon in the cast iron to give pure iron and carbon monoxide gas which escapes. F e 2 O 3 3 C → 2 F e 3 C O Limestone is then added as flux and it creates the slag. Impurities such as S Si pass into the slag and the slag later can be easily separated to yield pure iron.
Assertion For the extraction of iron haematite ore is used. Reason Haematite is a carbonate ore of iron. 1. Only the reason is correct 2. Both the assertion and reason are correct but the reason is not the correct explanation for the assertion. 3. Both the assertion and reason are correct and the reason is the correct explanation for the
Extraction of Iron from Haematite Ore (F e2O3) 1. Concentration by Gravity Separation. The powdered ore is washed with a stream of water. As a result the lighter sand particles and other impurities are washed away and the heavier ore particles settle down. 2.
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. Is haematite a carbonate ore

How is iron extracted from haematite Medium Solution Verified by Toppr Iron is extracted from its ore haematite in a blast furnace. The ore is led into the top of the furnace along with coke and limestone. The limestone decomposes in the hot furnace forming calcium oxide. This reacts with the sandy impurities (silicon dioxide) to form a slag.
Iron is extracted from its ore haematite in a blast furnace. The ore is led into the top of the furnace along with coke and limestone. The limestone decomposes in the hot furnace forming calcium oxide. In the extraction of iron from haematite the charge used is composed of haematite coke and lime stone in the weight ratio Medium.
We normally obtain iron from an ore called haematite which contains iron oxide. Page 3. Methods for turning the metal compounds in ores into metals depend on. Get Price. GCSE CHEMISTRY Extraction of Iron Haematite Limestone Slag . The main iron ore is called haematite. Haematite is iron(III) oxide Fe2O3.
Extraction of Metals. Extraction of Iron.. Iron is extracted from its ore in the blast furnace.. The main iron ore is called haematite. Haematite is iron(III) oxide Fe 2 O 3. The iron ore contains impurities mainly silica (silicon dioxide). Limestone (calcium carbonate) is added to the iron ore which reacts with the silica to form
Haematite ore being oxide ore is concentrated by gravity separation process using hydraulic separator. The oxide is being heavier settles to the bottom while lighter impurities come to the surface and is removed. 2. Calcination

Dec 5 2021The spongy iron moving down in the furance melts in the fusion zone and dissolved the impurities like C Si Mn phosphorus and sulphure. The molten iron collects at the bottom of furnace. The lighter slag floats on the molten iron and prevents its oxidation. The molten iron is removed and cooled in moulds. It is called pig iron or cast iron.
Summary of the process The orehaematite is crushed and mixed with coke and limestone. The mixture is called charge. The charge is loaded into the top of a tall furnace called blast furnace. Hot airthe blast is pumped into the lower part of the furnace. The ore is reduced to iron as the charge falls through the furnace.
