    iron ore market Mineralogy: hematite vs magnetite Iron ores can be formed of several different minerals; the most common are hematite and magnetite DSOs, including the midgrade products Rio Tinto and BHP produce from Australia’s Pilbara region and the highgrade 65% Fe fines Vale produces in Brazil, are predominantly hematite products Concentrates, meanwhile, can be either magnetite orMost large hematite iron ore deposits are sourced from altered banded iron formations and rarely igneous accumulations DSO deposits are typically rarer than the magnetitebearing BIF or other rocks which form its main source or protolith rock, but are considerably cheaper to mine and process as they require less beneficiation due to the higher iron content However, DSO ores can containIron ore WikipediaMagnetite and hematite are common ironoxides, being found in sedimentary, metamorphic and igneous environments and being associated with a wide variety of deposits styles, including orogenic gold, ironoxide coppergold and ironore deposits While the magnetic and mass properties of magnetite and hematite have been comprehensively studied, there is relatively limited publishedElectrical Properties of Magnetite and HematiteRich

  • Magnetite Wikipedia

    Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 3 O 4It 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 of· The majority of steel production is supported by iron ore sourced from highgrade hematite deposits, although a significant fraction comes from magnetite deposits Compared to direct shipping hematite ores mined from the upper regolith, magnetite deposits require significant beneficiation, which typically involves grinding to a particle size where magnetite is liberated from its silicateEcoefficient and costeffective process design for· The iron minerals that are at present used as ores are hematite, magnetite, limonite, and siderite; also, occasionally ankerite, goethite, and turgite Hematite is the most important iron ore The iron content of the pure minerals is as follows: Ankerite is a carbonate of lime, magnesia, manganese, and iron It is of valuable composition, carries only 14 or 15% of iron, and is used more forDifferent Types of Iron Ore 911metallurgist
