Dolomites.
Dolomite is an anhydrous carbonate mineral composed of
calcium magnesium carbonate
(with Fe, Mn, Co, Pb, and Zn
traces).
Formula of pure mineral : CaMg(CO3)2
(O = 52.06%, Ca = 21.73 %, Mg = 13.18 %, C
=13.03%)
Molar mass = 184,401 ± 0,008 g·mol-1
Not calcined dolomite.
Uncalcined dolomite is a mineral matter composed of
calcium and magesium carbonate.
Overall formula of the pure compound : CaCO3, nMgCO3 (n of
1 to 0.1).
Calcined dolomite.
Calcined dolomite is a mineral matter composed of
calcium carbonate and magnésium
oxyde.
Overall formula of the pure compound : CaCO3, nMgO (n of 1 to
0.1).
Calcined or sintered dolomite is a dolomite which has been subjected
to a high-temperature heat treatment (about 1 500 °C for
dead-burned (sintered) dolomite.
