Magnesite is a magnesium carbonate mineral with a chemical composition of MgCO₃. It is named after the presence of magnesium in its composition. ... Magnesite is used to produce magnesium oxide (MgO), which serves as a refractory material for the steel industry and as a raw material for the chemical industry.

What types of rock is magnesite?

Magnesite is a magnesium carbonate mineral (MgCO₃). Unlike related carbonates calcite (CaCO₃) and dolomite (CaMg(CO₃)₂), it is not a major rock-forming mineral. It most commonly occurs in metamorphosed igneous rocks which are rich in magnesium. These are ultramafic rocks like dunite, pyroxenite and peridotite.

Is Magnesite a rock?

Magnesite occurs as veins in and an alteration product of ultramafic rocks, serpentinite and other magnesium rich rock types in both contact and regional metamorphic terrains. These magnesites are often cryptocrystalline and contain silica in the form of opal or chert.

What is magnesite composed of?

Magnesite is a mineral that is composed of magnesium carbonate (MgCO3) and belongs to the calcite group of carbonate minerals. It is a major source of magnesium. The mineral formed as a result of the action of magnesium-containing solutions on calcite or as an alteration product from magnesium-rich rocks.

What is the metal of magnesite?

Magnesite, the mineral magnesium carbonate (MgCO₃), a member of the calcite group of carbonate minerals that is a principal source of magnesium. The mineral has formed as an alteration product from magnesium-rich rocks or through the action of magnesium-containing solutions upon calcite.
