Oxides Minerals

Home Minerals Oxides Minerals
Oxides form from the combination of a steel with oxygen. This group ranges from dull ores like bauxite to gem stones like rubies and sapphires. The magnetite pictured to the left is a member of this institution.

Manganite is a member of oxide minerals with composed of manganese oxide-hydroxide of formula: MnO(OH).A widespread and important ore of manganese. The mineral had been described by a number of different names since 1772, but was finally given its current name, which it owes to its manganese component, in 1827.


Chrysoberyl is a member of oxide mineral or gemstone with the formula: BeAl2O4.In spite of the similarity in their names, chrysoberyl and beryl are absolutely extraordinary stones, despite the fact that both include beryllium. Chrysoberyl is the third most commonplace herbal stone and is found at 8.5 at the Mohs


Chromite is an oxide mineral that an iron chromium oxide with formula: FeCr2O4. It is belonging to the spinel group. Chromite is the most important ore of chromium. Crystals are uncommon, but when found they are octahedral. Chromite is usually massive or in the form of lenses and tabular bodies, or it may be disseminated as granules.


Rutile is oxide group mineral with formula: titanium dioxide (TiO2). It often appears as pale golden, needlelike crystals inside quartz. When not enclosed in quartz, it is usually yellowish or reddish brown, dark brown, or black.


Ilmenite, otherwise called manaccanite, is a titanium-iron oxide mineral with formula: FeTiO3. It is a noteworthy wellspring of titanium. Typically thick and tabular, its crystals sometimes occur as thin lamellae (fine plates) or rhombohedra.. Ilmenite can also be massive, or occur as scattered grains. Intergrowths with hematite or magnetite are common


Corundum is a mineral that is primarily composed of aluminum oxide (Al2O3) and is one of the naturally occurring crystalline forms of aluminum oxide....


Spinel is the name of both an individual mineral and of a group of metal-oxide minerals that share the same crystal structure. Minerals in this group include gahnite, franklinite, and chromite. Spinel is found as glassy, hard octahedra, or as grains or masses.
