  • Magnetite Wikipedia

    Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces

  • On the Mechanisms of Silica (SiO2) Recovery in Magnetite

    Abstract. Magnetite (Fe 3 O 4) ore is concentrated by low-magnetic-field drums to recover a magnetite concentrate that is low in silica (SiO 2).The presence of SiO 2 in the magnetite concentrate for steel production increases the steel processing costs, so a major challenge in magnetic concentration is to lower the SiO 2 grade in the Fe concentrate. This work presents studies that were carried
