2010-03-06· During the extraction of iron, the reduction of iron oxides takes place in a blast furnace. In this process, hot air is blown from the bottom of the furnace and coke is burnt to raise the temperature up to 2200 K in the lower portion itself. The temperature is lower in the upper part. Thus, it is the lower part where the reduction of iron oxides (Fe2O3 and Fe3O4) takes place.
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

The blast furnace may be used in the extraction of iron from iron ore. Which one of the following is the correct balanced equation for the reaction between haematite (Fe 2 O 3 …
The carbon monoxide is the molecule that actually removes the oxygen from the iron oxide ore – this is the action of a reducing agent in the context of producing iron from iron oxide ores. REDOX definition reminders – reduction is a process of oxygen loss (or electron gain) and oxidation is a process of oxygen gain (or electron loss).
In summary, A mixture called the charge( iron ore-haematite, limestone-calcium carbonate, and coke-pure carbon) co … ntaining the iron ore is added through the top of the furnace. Hot air is blasted in through the bottom. After a series of reactions, liquid iron collects at the bottom of the furnace.
Determination of Iron in Ore by Redox Titration ... Note that the product of this reaction is FeCl3, and the iron is in the Fe3+ oxidation state. But the titration reaction requires Fe2+ so the iron must be reduced before it can be titrated. This is referred to as pre‐reduction. Have everything set up so that the pre‐reduction of the iron and the ceric ion standardization or titration can ...

3 - Extracting Iron - IGCSE Chemistry - Google Sites. Topic 03 - Simple chemical formulae & chemical equations 5.4 describe and explain the main reactions involved in the extraction of iron from iron ore The best known Iron ore is called Haematite (Haem - means Iron, as in Haemoglobin).
The production of iron from its ore involves an oxidation-reduction reaction carried out in a blast furnace. 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 ...
The process of the extraction of iron is carried out by the following steps: Concentration of ore Calcination or Roasting of ore Reduction of ore
