There is an endothermic heat of calcination that you will need to factor into your heat and material balance calculations. In addition calcined dolomite is friable. When it calcines it usually results in very fine particle size distribution. For sulfur capture limestone is a more effective sorbent compared to dolomite.

Deadburned dolomite is produced when dolomite is calcined at very high temperatures. It is used both as a refractory product in granular form to repair linings and for making the bricks used in the refractory linings of casting ladles and cement kilns.
Dolomite is also a good source of magnesium metal. The magnesium metal is extracted from dolomite by the wellknown ferosilicon decomposes completely above 900ºC. The product resulting from this relatively lowtemperature calcination is highly porous and reactive and is known as 'calcinated dolomite'.
