How steel is made
To make steel, iron ore is first mined from the ground. It is then smelted in blast furnaces where the impurities are removed and carbon is added. In fact, a very simple definition of steel is "iron alloyed with carbon, usually less than 1%." Blast furnaces require many auxiliary facilities to support their operations.
Fact sheet Hydrogen (H2)-based ironmaking

How we make steel
Making steel. At Scunthorpe, we use the Basic Oxygen Steelmaking (BOS) process – our modern convertors (or vessels) take a combined charge of scrap and liquid iron of up to 330 tonnes and convert this into steel in just 25 minutes. When the liquid iron arrives at the BOS Plant, it's poured from the torpedoes into refractory-lined charging ...
Iron processing
The partially reduced ore is then smelted in the second unit, and liquid iron is produced. Smelting-reduction technology enables a wide range of coals to be used for iron making. Iron processing - Ores, Smelting, Refining: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments.
Iron Ore Supply Chain: From Mining to Steel Production
Iron ore is transported from the mine to the steel mill through a supply chain that includes mining, processing, and transportation. The supply chain can be complex, with multiple stakeholders involved in each step of the process. To ensure a reliable supply of iron ore, steel companies often sign long-term contracts with mining companies.
Sustainable steel through hydrogen plasma reduction of iron ore
Iron- and steelmaking is the largest single industrial CO 2 emitter, accounting for 6.5% of all CO 2 emissions on the planet. This fact challenges the current technologies to achieve carbon-lean steel production and to align with the requirement of a drastic reduction of 80% in all CO 2 emissions by around 2050. Thus, alternative reduction technologies …
