Steel products after processing of iron ore

Apr 21, 2020

Next Generation Iron Ore Technology and Products Minnesota's Mesabi Iron Range has long served the domestic steel industry with iron ore. By the end of WWII, all of the lean ore (unprocessed, direct-ship) was mined out. A University of Minnesota researcher developed the process for turning low-grade ore (taconite) into pellets that could replace the lean ore in blast furnaces

    Iron ore being unloaded at docks in Toledo, Ohio. Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe

    Steel is an alloy made up of iron with typically a few tenths of a percent of carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant need typically an additional 11% chromium.Because of its high tensile strength and low cost, steel is used in buildings
