Video Transcript. In this video, we will look at the extraction of iron from its ore in the blast furnace. We’ll look at the chemicals used in a blast furnace and the temperatures involved. Iron is an abundant metal, which is relatively cheap to produce. Ores containing a high proportion of iron can be found throughout the world.

The blast furnace. The blast furnace is used industrially to extract iron from its ore. Most of the iron produced in the blast furnace is usually turned into steel. The diagram below shows the main parts of the blast furnace with a brief description of what they do. Iron ore, mostly haematite (Fe2O3) is mixed with coke and limestone and dropped

Step 1: The Iron ore is crushed and broken into smaller pieces, concentrated with gravity separation process (washed with water). Step 2: The raw materials are added into the top of the furnace : Iron ore (Haematite, Fe2O3), Coke (Carbon, C), Limestone (CaCO3) Step 3: It is heated by blowing hot air at the base of the blast furnace.

1 · Iron, when extracted from iron ore such as haematite containing iron (III) oxide, Fe2O3, in a blast furnace is called iron extraction blast furnace metallurgy. In this reduction reaction, oxygen is removed from the iron (III) oxide to leave behind iron. Generally, the extraction of metals and their isolation are based on three major procedures.

A metal ore is a rock that contains enough of the metal to make it worthwhile extracting. They have to be extracted from their ores through processes such as electrolysis, using a blast furnace or by reacting with more reactive material. In many cases the ore is an oxide of the metal, therefore the extraction of these metals is a reduction

4.1.6.3.1: Iron Production. 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.
