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.
Magnetite Mines Ltd says it has entered into an exclusivity agreement with ore sorting technology company NextOre to use its leading-edge magnetic resonance ore sorting technology for pre-concentration of magnetite and iron ore projects.
With all of hematite's many varieties, it is natural that some of them can be easily confused with other metallic minerals. All of the hematite varieties though, exhibit the same distinctive red to red-brown streak when scratched across a rough hard surface, which should serve to distinguish hematite from similar-appearing minerals.
Sep 10, 2019· The Group PLC (), one of the world's premium providers of highly engineered mining equipment and services, has been awarded a £100 million order to provide industry-leading energy saving solutions to the Iron Bridge magnetite project, a joint venture between Fortescue Metals Group Ltd subsidiary FMG Magnetite Pty Ltd and Formosa Steel IB Pty Ltd.
Magnetite is found in large quantities in North and South America, Europe, and New Zealand. Magnetite is eroded into rivers and carried to the beach, where it accumulates in sand. It is then concentrated via wave action and currents. In the United States, large quantities of high-quality magnetite have been mined in New Jersey and Vermont.
Apr 25, 2017· The bulk of these rocks are either Hematite or Magnetite, ... The region forms three of the eleven biggest mining operations in the world. In 2015, Australia produced 824 million tons of iron ore and in 2014 was 774 million tons which represent more than 20% of the global output.
More than 90% of South Australia's iron ore is magnetite located in several prospective areas of the state, stretching from the Eyre Peninsula to the Braemar province and the Far North.; Approximately 2.3 million tonnes of magnetite was produced in South Australia in 2018 for domestic use and export while there are a number of magnetite projects in various stages of development.
Magnetite is widely distributed usually with octahedral, or spherical, morphology, in igneous and metamorphic rocks. Magnetite is also found in limestones, in fumerolic deposits, and in living forms. For the latter the mineral plays some very important role, which we highlight in Section 8.04.3.3.2.

Magnetite is an important ore of iron. Well formed crystals are popular among mineral collectors, and the magnetic Lodestone variety is frequently sold in hobby shops to amateur collectors. Magnetite is also of significant interest to the science community due to its strong magnetic properties.
Magnetite Mines Ltd says it has entered into an exclusivity agreement with ore sorting technology company NextOre to use its leading-edge magnetic resonance ore sorting technology for pre-concentration of magnetite and iron ore projects.
World production averages two billion metric tons of raw ore annually. The world's largest producer of iron ore is the Brazilian mining corporation Vale, followed by Anglo-Australian companies Rio Tinto Group and then BHP Billiton.
Magnetite ore has the highest proportion of iron, at 65%. Haematite ore also has a high content of iron at 60%. All iron ore contains ferric oxide and it is from this that iron is extracted. Approximately two billion tonnes of iron ore are mined each year. The pictogram / graph below, shows the world distribution of iron ore mining.
