Who we are

GRECIAN MAGNESITE is a privately owned company established in 1959 as a mining and industrial concern. However, the magnesite mining expertise goes back to 1914.

GRECIAN MAGNESITE is a magnesite specialist. The company produces and supplies Caustic Calcined Magnesia, Deadburned (Sintered) Magnesia, Magnesium Carbonate (Raw Magnesite) and Basic Monolithic Refractories.
