Sometimes the magnesite is calcined, and the magnesia thus obtained used instead.
The base of this manufacture is the magnesite of Baldissero.
The most important use of magnesite is as a refractory material for lining furnaces and converters.
magnesite mines are worked by an Anglo-Greek company in Euboea.
The commoner type of magnesite deposits is represented by those of Greece, California, Venezuela, and many other countries.
For every ton of steel produced five pounds of magnesite is needed.
The Canadian magnesite is of lower grade than the domestic and European magnesite and is consequently less desirable.
In 1913 the American production of magnesite was only 9600 tons.
Made with calcined magnesia (obtained from magnesite) and chloride of magnesium.
It is cheaper but less satisfactory than magnesite, and is not likely to be used on any large scale.
