Iron processing Britannica
Iron processing, use of a smelting process to turn the ore into a form from which products can be fashionedIncluded in this article also is a discussion of the mining of iron and of its preparation for smelting Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive magnetic properties It constitutes 5 percent by weight of the Earth’s crust, and it is the Concentration refers to the methods of producing ore fractions richer in iron and lower in silica than the original material Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed and ground to release the ore minerals from the gangue Magnetic techniques also are usedIron processing Ores BritannicaThe 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 Iron processing Iron making Britannica
Steelmaking Wikipedia
Steelmaking is the process of producing steel from iron ore and/or scrapIn steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel RSNZ 'Big Science' Documentary Making Competition 2006, entry by Pukekohe High School students Tim, Alec AllenIron Production Process YouTubeDirect reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal Many ores are suitable for direct reductionDirect reduced iron Wikipedia

Iron Ore production in the Pilbara Rio Tinto
Processing of the ore ranges from simple crushing and screening to a standard size, through to processes that beneficiate or upgrade the quality of the iron ore products This is done by physical processes, which remove impurities by differences in particle density or size gravity or size separation Processing may be wet or dryJan 25, 2019 The manufacture of iron is based on the principle of reduction of iron oxide with carbon monoxide This reduction process is carried out in a furnace called ‘blast furnace’ The iron ore is first washed concentrated roasted in order to remove impurities such as sulphur and phosphorus as oxidesWhat are the manufacturing processes of iron?
