Magnetic Properties Of Iron Ore

Use of Magnetite as an Ore of Iron. Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite, hematite, and chert. Once considered a waste material, taconite became an important ore after higher grade deposits were depleted. Today's commercial taconites contain 25 to 30 iron by weight.

  • Iron Ore Magnetic Properties

    Dec 31, 2018 Like hematite ores, magnetite ores require initial crushing and screening but also undergo a second stage of processing using the magnetic properties of the ore to produce a concentrate. Further processing of magnetite involves agglomeration 4 and thermal treatment of the concentrate to produce pellets. These can be used directly in blast.In this work, low temperature hydrogen reduction of hematite ore fines was performed in a fixed bed reactor with a stirring apparatus, and a laboratory Davis magnetic tube was used for the magnetic separation of the resulting magnetite ore fines. The properties of the raw hematite ore, reduced products, and magnetic concentrate were analyzed.
