The main raw materials for steelmaking are molten iron or pig iron with high carbon content and scrap iron and steel. In order to remove impurities in the molten iron, it is also necessary to add oxidizers, deoxidizers, slag-forming materials, and ferroalloys to the molten iron to adjust the composition of the steel.
The Making of Iron & Steel
2 Materials Used to make Steel 2.1 Iron Ore Composition Iron very rarely occurs in the earth's surface as a metal. It is widely distributed, combined with oxygen as iron oxides. In fact it is believed that iron makes up about 5% by weight of the earth's crust. Geologists recognise various types of iron ore, classified chiefly according to iron (Fe)

FINEX (steelmaking process) - Wikipedia
FINEX is the name for an iron making technology developed by former Siemens VAI (now Primetals Technologies) and POSCO.Molten iron is produced directly using iron ore fines and non-coking coal rather than traditional blast furnace methods through sintering and reduction with coke.Elimination of preliminary processing is claimed to make the plant for FINEX less expensive to build than a blast ...
Blast furnace - Wikipedia
The primary advantage of the early blast furnace was in large scale production and making iron implements more readily available to peasants. Cast iron is more brittle than wrought iron or steel, which required additional fining and then cementation or co-fusion to produce, but for menial activities such as farming it sufficed.

Making Steel Scrap steel. Steel that has been previously manufactured and used, and which has then come to the end of its life in that form, can be infinitely recycled. As such, it is another important raw material in steelmaking. There are about 20 different grades of scrap that can make different types of new steel.
Steel Production - American Iron and Steel Institute
How Steel Is Made. Steel is primarily produced using one of two methods: Blast Furnace or Electric Arc Furnace. The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved ...
How is Steel Made? | Metal Casting Blog
At the most basic, steel is made by mixing carbon and iron at very high temperatures (above 2600°F). Primary steelmaking creates steel from a product called "pig iron.". Pig iron is smelted iron, from ore, which contains more carbon than is correct for steel. The steelmaker uses a system that bubbles oxygen through melting pig iron.
