The formation of magnetite in the early Archean oceans ...

2017-5-15  Magnetite is formed by the reaction between ferric iron mats and Fe (II) anaerobically. Magnetite could precipitate directly in the Archean ocean. The high temperature and high Fe (II) seafloor vents fluids favors magnetite deposition. The oxygenation and cooling of Palaeoproterozoic ocean shuts off this mechanism.

Magnetite - an overview ScienceDirect Topics

Magnetite is widely distributed usually with octahedral or spherical morphology in igneous and metamorphic rocks. Magnetite is also found in limestones, in fumarolic deposits, and in living forms. For the latter, the mineral plays some very important role, which we highlight in Sections 10.4.3.3.2 and 10.4.3.3.3. Black magnetite, with a ...

2013-11-8  Forms of Iron Minerals, Ores, and Rocks Iron occurs mainly in iron-oxide ores. Some ores are a mixture of minerals rich in iron. Other iron ores are less rich and have a large number of impurities. The most important iron ore-forming minerals are: • Magnetite - Magnetite (Fe3O4) forms magnetic black iron ore. There are large deposits of

Mineralisation and Ore Type – Karara Mining

Magnetite. Karara comprises a large-scale, long-life magnetite orebody amenable to bulk mining and processing. Magnetite ore has lower iron content (34-36% Fe) than hematite ore (58-64% Fe). It must be upgraded by a complex ore treatment process (beneficiation) to produce a high-grade (+65% Fe) concentrate for steelmaking.
