2a. Extraction of Iron in a blast furnace. Sadly, now shut down! Raw Materials. Iron Ore e.g. haematite ore (iron(III) oxide) the source of iron.. Fe 2 O 3; or magnetite ore. Fe 3 O 4; coke (carbon, C), both fuel and reducing agent.; hot air (for the oxygen in it) to burn the coke. O 2; limestone (calcium carbonate) to remove certain impurities like silica.
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 process since oxygen is being removed
Iron Extraction Manufacturing Process - Blast Furnace Method. Iron is extracted from different ores exist in the world. Hematite (Fe 2 O 3) is reduced to iron metal in the blast furnace under several steps. Limestone and coke are used as other raw materials to generate heat and reducing agents.
Higher and foundation tiers . 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 is extracted in a large container called a blast furnace from its ore, hematite Modern blast furnaces produce approximately 10,000 tonnes of iron per day The process is demonstrated and explained below: Diagram showing the carbon extraction of iron. The raw materials: iron ore (hematite), coke (an impure form of carbon), and limestone are ...
Iron processing - Smelting, Refining, Alloying: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.
To realize the resource utilization of the valuable metals in the titanium-containing blast furnace slag, the process route of "hydrochloric acid leaching-electrolysis-carbonization and carbon dioxide capture-preparation of calcium carbonate" was proposed. In this study, the influences of process conditions on the leaching rates of calcium, magnesium, aluminum, and …
In a blast furnace used for the extraction of iron, carbon reacts with oxygen from the air to form carbon monoxide. ... Iron from a blast furnace contains about 5% of the impurities – carbon, silicon, phosphorus and sulfur. Most of this impure iron is used to make steels, such as mild steel, and a very small percentage is used to make pure ...

Blast furnaces produce pig iron from iron ore by the reducing action of carbon (supplied as coke) at a high temperature in the presence of a fluxing agent such as limestone.Ironmaking blast furnaces consist of several …
Ironmaking Blast Furnace. Iron is made by reacting iron ore (iron oxide and impurities), coke (a reductant) and limestone (CaCO 3) in a blast furnace. Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities. The iron ore is dressed or crushed into 0.5-1 in. chunks ...
Extraction of Metals. Extraction of Iron.. Chemistry of the blast furnace ().. Limestone is calcium carbonate (CaCO 3) and it is added to the blast furnace to remove the impurities in the iron ore. Calcium carbonate is decomposed by heat in the furnace to give calcium oxide and carbon dioxide. This is called thermal decomposition (see examples of other carbonates). ...
(b) A basic oxygen furnace is being filled with molten iron from a blast furnace. Pyrometallurgy in the Extraction of Magnesium The Pidgeon process is one of the methods of magnesium metal production via a high temperature (800-1400°C) process with silicon as the reducing agent (instead of carbon for iron extraction).
