Extraction of Iron Metallurgy Blast Furnace and Reactions

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. What happens in the Blast Furnace? The purpose of a Blast Furnace is to reduce the concentrated ore chemically to its liquid metal state.

Iron Extraction by Blast Furnace Metallurgy Procedure

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.

Iron Production Chemistry LibreTexts

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 iron.

GCSE CHEMISTRY Extraction of Iron Haematite

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 molten calcium silicate in the blast furnace.

How Is Iron Extracted From the Earth? Reference

26-03-2020  Magnetite and hematite are iron oxides; however, the extraction of iron from an iron oxide involves a series of steps that begins when mined iron ore is crushed into smaller pieces by a crusher and then washed. The second step in the process is calcination or roasting of the ore, which removes certain impurities, carbon dioxide and other substances.
