    Jan 01, 2015· The ore is mainly composed of magnetite, hematite, martite, and quartz. It is very difficult to produce a highquality iron ore concentrate by magnetic separation alone for this type of iron ore. The ore is first ground using ball mills down to about 90% 75 μm. Drum LIMS are then used to take out the magnetite particles, while drum MIMS ( ...

  • Difference Between Magnetite and Hematite | Definition ...

    Jan 31, 2018· Magnetite is an iron ore where iron can be found in the form of Fe 3 O 4. Magnetite is ferromagnetic, which means, magnetite particles are attracted to an external magnetic field; magnetite particles can act like tiny magnets when magnetized. Magnetite is ferromagnetic since it has both Fe 2+ and Fe 3+ ions that have many unpaired electrons.

  • Iron | Geoscience Australia

    In the Earth's crust iron is found mainly as minerals of iron oxide such as hematite, magnetite, goethite and limonite. The minerals that are mostly used as ore for making iron are hematite (Fe 2 O 3) and magnetite (Fe 3 O 4). Iron is quite soft and easily worked, but it has a very high melting point of 1538°C.

  • Iron processing Ores | Britannica

    The most widely distributed ironbearing minerals are oxides, and iron ores consist mainly of hematite (Fe 2 O 3), which is red; magnetite (Fe 3 O 4), which is black; limonite or bogiron ore (2Fe 2 O 3 ·3H 2 O), which is brown; and siderite (FeCO 3), which is pale brown. Hematite and magnetite are by far the most common types of ore.
