The conventional route, aka the indirect reduction method, for making steel consists of sintering or pelletization plants, coke ovens, blast furnaces, and basic oxygen furnaces.
spong iron is the porous product of direct reduction of iron ore .it is better than scrap of iron because of less polution of the environment and more homogenous and have less harmfull element such as phosphor sulphur( S and P).

Spiral Concentrators are used in Iron ore beneficiation plants for Gravity Separation. It separates the higher density Iron Ore from Silica based on density difference as concentrate, middling & tailing.

direct reduction: FeO + C = Fe + CO indirect reduction FeO + CO = Fe + CO2 I don't think that is what the terminology 'direct reduction' means in this context. For a start most directly reduced iron (DRI) is produced using CO and H2 produced from natural gas. I think the correct meaning is that 'direct reduction' is called direct because it directly produces iron (as a solid sponge because iron has a high melting point - see the 'bloomery process' for producing wrought iron), while the indirect process produces iron via 'pig iron' which is a high carbon alloy of iron (produced as a liquid because of the reduction in melting point caused by the carbon - see 'Osmond' process).
Carbon monoxide and hydrogen are typically used in the reduction process of iron ore, where they react with the iron oxide to produce metallic iron. This process is commonly known as the direct reduction process or the Midrex process.
Iron ore is the primary source of iron in a blast furnace. It undergoes a series of reactions, including reduction, to produce molten iron. The iron ore also helps to remove impurities, resulting in high-quality iron production.
Methane gas can reduce iron oxide to iron metal. This process was first tried and tested in Mexico by the method of HYLSA Hojalata y Lamina Sociedad Anonima. Now the process is used in the plant Lazaro 'Cardenas Mexico to produce direct reduced iron ore to iron sponge.
Heat-reduction with Carbon (coale)
The extraction of iron from its ore using carbon is a reduction reaction, specifically a redox reaction. Carbon reduces the iron oxide in the ore by donating electrons to the iron, resulting in the formation of elemental iron and carbon dioxide.
Iron is created in the process of metal production through the reduction of iron ore in a blast furnace. The iron ore is heated with carbon, which removes oxygen from the ore, resulting in the formation of molten iron. This molten iron is then cast into molds to create various iron products.
Sponge iron is produced by reducing iron ore pellets in a direct-reduction process, whereas pig iron is produced by melting iron ore with a high-carbon fuel in a blast furnace. Sponge iron is mainly used as a raw material for steelmaking in electric arc furnaces, whereas pig iron is typically used in the production of cast iron and wrought iron products.
Limestone helps remove impurities (silica, alumina) from the iron ore, forming slag. Coke serves as a reducing agent, reacting with the iron ore to produce carbon monoxide for the reduction process. Iron ore provides the iron for the production of steel in the blast furnace.
No, iron is not extracted from its ore through electrolysis. Iron is typically extracted from its ore through a process called reduction, where the ore is heated with a carbon source to remove the oxygen and transform the ore into metallic iron. Electrolysis is more commonly used for extracting reactive metals like aluminum and magnesium.
Iron smelting isn't something that can be done (at all) in the kitchen or in a typical home. Driving the last oxygen atom off of iron requires temperatures in excess of 1250 degrees centigrade (around 2300F), so you need a forge, furnace, or kiln capable of reaching those temperatures. Then you also need to control the atmosphere inside the hot space so that it doesn't contain any free oxygen. This can be done by adding graphite, coke, or lump (not briquette!) charcoal. Iron smelting is a big, hard, task, and not usually done "at home".
Yes, heating the ore in the presence of carbon can be used to extract iron from the ore through a process called reduction. The carbon reduces the iron oxide in the ore to elemental iron, leaving behind carbon dioxide gas. This process is commonly used in the production of iron and steel.
