LKAB Minerals offer a range of Magnesites, including Dead Burnt Magnesite, SKLS Magnesite, and Nedmag Magnesia, for a number of refractory applications.
Magnesite is a natural ore identified as magnesium carbonate, occurring as a primary mineral in igneous and sedimentary rocks.
Dead Burnt Magnesite is made by calcining the magnesite ore in a rotary kiln to produce a high-purity product with high purity, stability, and 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.
