| Résumé | (disponible en anglais seulement)
Brucite is a natural magnesium hydroxide [Mg(OH)2] particularly sought after for its flame-retardant properties, as a raw mineral for the production of caustic
or dead-burned magnesia, a variety of other industrial mineral uses, and as a high-grade ore mineral for the production of magnesium metal. Brucite has an advantage over magnesium carbonates, such as magnesite and dolomite, because it does not
contain CO2 in its crystal structure. Consequently, there is no CO2 released during the calcining or other processing of this mineral except from fuel combustion. This advantage may become even more important in the future as CO2 is considered the
main greenhouse gas contributing to global warming. Carbonate-hosted contact metamorphic/metasomatic (skarn-type) brucite deposits have the best economic potential. The sequence of calcosilicate metamorphic index minerals starting from
unmetamorphosed magnesium-bearing carbonate (dolostone or magnesite-bearing rock) to igneous intrusion contact consists of talc, tremolite, forsterite and brucite/periclase. This sequence can be used to focus exploration efforts. The current
worldwide brucite market is probably less than 100,000 t/y but it is increasing rapidly. High-grade brucite deposits are expected to become hot exploration targets over the next few years. |
