Magnetite (Fe 3 O 4) is a common iron oxide mineral.It is a member of the spinel group. These are minerals that share the same structure but differ in chemical composition. Other notable members of the group are chromite and spine
Hematite, also spelled as haematite, is the mineral form of iron(III) oxide (Fe 2 O 3), one of several iron oxides.It is the oldest known [clarify] iron oxide mineral and is widespread in rocks and soils.
Worldwide suppliers of Industrial Minerals since 1948. We ship minerals to Europe, Africa, America, the Middle East and beyond.
Dolomite: Dolomite, type of limestone, the carbonate fraction of which is dominated by the mineral dolomite, calcium magnesium carbonate [CaMg(CO3)2]. Along with calcite and aragonite, dolomite makes up approximately 2 percent of the Earth’s crust.
Detailed description, properties, and locality information guide about the magnetic mineral magnetite.
A Little About Us. At Qualtiy Magnetite, we globally source, process, and distribute magnetite – a type of iron oxide that possesses natural magnetic properties.
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.Magnetite is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself.
Interactive guide to hundreds of rocks and minerals.
Australia’s iron ore reserves and resources are in both hematite and magnetite ores. Because of the high average grades (% Fe) of hematite ores when compared to the average grades for magnetite ores, it is necessary to report national resources in terms of contained iron.
Meteorite Minerals. The following descriptions of meteorite minerals are not exhaustive, but should give you an idea of some of the important components of meteorites.
