This is how iron ore is turned into steel Business Insider

2017-11-1  Once the pig iron ore has been produced it is sent to an basic oxygen furnace, or BOF, to turn it into steel. Molten iron from a blast furnace is “charged” (poured from a ladle) into the BOF ...

2018-11-19  With ore-based production, steel is mainly produced from pig iron. The carbon content is reduced through decarburisation with oxygen in a BOF (Basic Oxygen Furnace) converter. The necessary energy for the temperature increase is obtained from the oxidisation reactions, C to CO 2 and Si to SiO 2 , which generate a lot of heat.
