Magnesia

Magnesia is the term for magnesium oxide (formula: MgO). Magnesia is produced by mining and processing mainly the hard rock mineral, magnesite, which occurs in two main forms: cryptocrystalline and crystalline. Rarely, magnesia may be produced from other hard rock minerals such as dolomite, brucite, huntite, and serpentinite.

Our Process & Magnesia Facts about Magnesium Oxide …

In the production of magnesia products from naturally-mined sources, magnesium carbonate (magnesite) is heated from 700°C to 1000°C and thermally decomposes to produce magnesium oxide and carbon dioxide: MgCO 3 + heat –> MgO + CO 2 (gas) MgCO 3 = magnesite. MgO = magnesium oxide. CO 2 (gas) = carbon dioxide.
