The coke "steals" the oxygen from the iron oxide (in a chemical process called reduction), leaving behind a relatively pure liquid iron, while the limestone helps to remove the other parts of the rocky ore (including clay, sand, and small stones), which form a waste slurry known as slag. The iron made in a blast furnace is an alloy containing ...

Source: Quora. Iron Age metallurgists alternated adding charcoal and iron ore powder. After a few days, they lowered the temperature and extracted a bloom, which is a mass of iron and steel mixed with slag. In the photo below, you can see what a bloom looks like: the shiny bit is steel, the dull gray part is iron, and the black bits are slag.

It is easy to extract iron from this kind of haematite by using gravity separation and magnetic separation. Mediumgrained hematite refers to iron ore with an embedded particle size between and 2mm. This type of hematite is also relatively easy to select, mainly using gravity separation, magnetic separation and magnetic roasting.

Steelmaking. Steelmaking is the process of producing steel from iron ore and/or scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (the most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce ...

Download. Iron (Fe) is a metallic element that constitutes % by weight of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). Hematite is an iron oxide mineral.
