· Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides. As a result of these impurities, iron must be first separated from the gangue and then converted to pure iron.
iron and oxygen gas react to form iron oxide according to the chemical equation below 4 Fe +3 O2 = 2 Fe2O3 how many atoms of iron are required to react with mol O2 Iron(III) oxide (Fe ) is produced according to the following equation: 4 Fe(s) + 3 0...
(a)€€€€ Iron that is extracted from its oxide by carbon reduction in a blast furnace is called cast iron. Cast iron contains about 4% carbon. This carbon makes cast iron very brittle. €€€€€€€€€ Carbon steels can be made by the following processes. •€€ Blowing oxygen into molten cast iron to remove most of the carbon.
Iron III Oxide is Fe2O3. The molar mass is 2 x + 3 x 16 = g/mol So, the iron is / = times the mass of Fe2O3. 10kg of iron would require 10/ = .

Iron is one of the most abundant metals of the Earth's crust. It occurs naturally in water in soluble form as the ferrous iron (bivalent iron in dissolved form Fe 2+ or Fe(OH) +) or complexed form like the ferric iron (trivalent iron: Fe 3+ or precipitated as Fe(OH) 3).The occurrence of iron in water can also have an industrial origin ; mining, iron and steel industry, metals corrosion, etc.
Extraction of iron is based on the reduction of HAEMATITE (Fe 2 O 3) with carbon.. The process of the extraction of iron is carried out by the following steps: In this metallurgical operation, the ore is concentrated by removing impurities like soil etc. The. process involves the crushing and washing of .
· Iron(III) oxide and carbon monoxide to produce iron(II) oxide and carbon dioxide. This reaction takes place at a temperature of 500600°C. ce{3Fe2O3 + CO >[400 C] 2Fe3O4 + CO2} Iron(III) oxide react with carbon monoxide to produce iron(II,III) oxide and carbon dioxide. This reaction takes place at a temperature near 400°C.
Extraction of Metals. Extraction of Iron.. Chemistry of the blast furnace.. Hot air is blasted into the furnace causing coke (carbon) to burn rapidly producing carbon dioxide and raising the temperature to 2000 °C.. carbon + oxygen carbon dioxide + heat. C (s) + .
Blast furnaces extract pure iron from the iron(III) oxide in iron ore in a two step the first step, carbon and oxygen react to form carbon monoxide: 2C (s) + O2 (g) → 2CO (g)In the second step, iron(III) oxide and carbon monoxide react to form iron and carbon dioxide: Fe2O3 (s) + 3CO (g) → 2Fe (s) + 3CO2 (g)Write the net chemical equation for the production of iron from .

· The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes .
