    Iron processing Britannica

    Throughout the 20th century, many new iron-making processes were proposed, but it was not until the 1950s that potential substitutes for the blast furnace emerged. Direct reduction, in whichiron oresare reduced at temperatures below the metal’s melting point, had its origin in such experiments as the Wiberg-Soderfors process introduced in Sweden in 1952 and the HyL process introduced in Mexico in …

    Iron ore BHP

    Iron ore is mixed with coke (from super-heated metallurgical coal) in a blast furnace. Air that has been heated to around 1,200 degrees Celsius is injected into the furnace, creating a flame temperature of 2,000 degrees. This converts the iron ore to molten pig iron and slag. Then, impurities are removed and alloying elements are added.
