Magnesia is produced largely by the calcination of natural minerals (~89%), principally magnesite, and rarely from brucite (Mg(OH) 2, dolomite (CaMg(CO 3) 2) or hydromagnesite (Mg 5 (CO 3) 4 (OH) 2 ·4H 2 O). About 11% is produced synthetically by calcination of Mg(OH) 2 derived as a precipitate from seawater and brines (Fig. 1). The …

The replacement, when taking place in geological past, likely included several phases of progressive influx of magnesium (Mg) rich fluids into existed dolomite sediment. On the molecular basis, the incursion resulted in a near complete removal of Ca+2 from chemical structure of the sediment and a fill up of available vacancies with Mg+2.
