magnetite iron deposits

Trace Elements in Magnetite from Massive Iron Oxide

These magnetite-bubble pairs buoyantly segregate and become a rising magnetite-fluid suspension that deposits massive magnetite along or in proximity to regional-scale transcurrent faults. Kiruna-type iron oxide-apatite deposits should not be confused with another type of IOA deposits: nelsonites.

All about skarns

Nov 02, 2007Iron skarns are mined for their magnetite content and although minor amounts of Cu, Co, Ni, and Au may be present, iron is typically the only commodity recovered (Grigoryev et al., 1990). Many deposits are very large (500 million tons, 300 million tons contained Fe) and consist dominantly of magnetite with only minor silicate gangue.

Understanding Iron Ores and Mining of Iron Ore – IspatGuru

Apr 03, 2015Over 300 minerals contain iron but five minerals are the primary sources of iron ore. They are (i) magnetite (Fe3O4), (ii) hematite (Fe2O3), (iii) goethite (Fe2O3.H2O), (iv) siderite (FeCO3), and (v) pyrite (FeS2). The first three are of major importance because of their occurrence in large economically minable deposits.

Iron Ore Statistics and Information

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries.
