Domestic Production and Use: In 2019, mines in Michigan and Minnesota shipped 98% of the usable iron ore products consumed in the steel industry in the United States with an estimated value of $5.4 billion, an increase from $4.6 billion in 2018. The remaining 2% of domestic iron ore was produced for nonsteel end uses. Seven open-pit iron
Introduction The production of iron from its ore involves a redox reaction carried out in a blast furnace. The furnace is filled at the top with the iron ore oxide most commonly hematite ( F e 2 O 3) but can also magnetite ( F e 3 O 4 ), carbon called coke and limestone ( C a C O 3 ).

Today, no one process is solely used to process steel. A blast furnace processes most iron ore, creating pig iron. The basic oxygen process is used to create steel using the pig iron and electric arc is used to produce steel from plentiful scrap, although either method can process pig iron or scrap iron.
