WebDec 21, 2024 · As for the iron that humans have worked and forged for millennia, it’s an amalgamation known as iron oxides. The process of recovering iron from iron ores starts with mining processes, stripping the earth’s outer layers that contain this metal. Iron ore then gets converted into various versions of what we call “iron” today. WebJun 13, 2024 · Inside the vessel, iron oxides are dissolved in a mixture of molten metal oxides such as silica, magnesia, and quicklime, all heated to about 1,600 °C by an electric current. At the cathode, this current reduces iron ions to form a pool of liquid metal that is ready for final refining.
