Sa Magnesite is a natural ore identified as a magnesium carbonate, occurring as a primary mineral in igneous and sedimentary rocks. LKAB Minerals offer a range of Magnesites including Dead Burnt Magnesite, SKLS Magnesite and Nedmag Magnesia for a number of refractory applications.
Dead Burnt Magnesite is made by calcining the magnesite ore in a rotary kiln to produce a high purity product that has high purity, is stable and has good sintering properties.
SKLS Magnesite, also known as Periclase, is made using a calcination and seawater process.
Nedmag 99 is a high purity synthetic Dead Burned Magnesia produced by Nedmag Industries. It has a magnesia content of 99% min.
