Dolomite is also a good source of magnesium metal. The magnesium metal is extracted from dolomite by the wellknown ferosilicon process. Dolomite decomposes completely above 900ºC. The product resulting from this relatively lowtemperature calcination is highly porous and reactive and is known as ''calcinated dolomite''.
