    Magnetite ore, long the leading source of domestic iron supply in North America, Europe and China, is now increasingly relevant across the globe. The perception that magnetite ore is an inferior substitute to hematite ore is now firmly changing. As easily accessibly, economic hematite deposits become rarer, magnetite ore will continue to emerge as an []

  • How to use magnetite iron ore to make sponge iron in coal

    the idea of the process of how to make sponge iron from iron ore is basically to add coal to remove oxygen from iron by adding non coking coal and to remove sulfur by adding lime stone,the iron ore and coal are crushed in crushers and screened to the recommended sizes (5mm- mm),then mixed and heated to degrees centigrade s,the mixture is treated in rotary kiln process with air control

  • What Is Magnetite Used For In A Coal Washing Plant

    The mine was started in 1949 and the coal washing plants are ten years old. Mark Whitter, New Clydesdale Coal plant manager, says that magnetite is used as a medium to separate coal at the plant and the old separators were no longer considered to be efficient.

  • Magnetite Wikipedia

    Huntington patients have not shown increased magnetite levels; however, high levels have been found in study mice. Applications. Due to its high iron content, magnetite has long been a major iron ore. It is reduced in blast furnaces to pig iron or sponge iron for conversion to steel. Magnetic recording

  • SPONGE IRON PLANT

    Iron ore crushing is not required since sized material has to be purchased. Iron ore of size 5 mm to 20 mm is being used for the production of Sponge iron. Iron ore is being fed to the Ground hopper, from where it conveyed to the Screen with the help of Vibro Feeder, where Oversize i.e. + 20 mm and Undersize i.e. 5

  • What Are the Uses of Magnetite? Reference

    04.08.2015· Magnetite is also used as a source of iron to manufacture iron-based chemicals and fertilizers. Ferric chloride and ferric sulphate are manufactured with magnetite as one of the starting materials. These chemicals are effective in clarifying raw water in water purification plants. The dark, glossy nature of magnetite ore has led to its use in landscaping as accent rocks.

  • Sponge Iron an overview ScienceDirect Topics

    Recently a variant of COREX process, FINEX, is codeveloped by VAI and Posco for the production of hot metal based on the direct use of iron ore fines and noncoking coal. Fine iron ore is charged into a series of fluidized-bed reactors together with fluxes. The iron ore fines pass in a downward direction through four reactors where they are heated and reduced to DRI by means of a reduction gas

    In this method, heat coal (as a reducing agent) is mixed with iron ore and sponge iron is produced in a horizontal furnace. Input iron ore: In the Midrex or HYL process, it is generally recommended to use high quality cooked pellets with a maximum of about 30% iron ore lumps. Up to 100% of the lumps can be used in this process and some types of
