Abstract:

Processes are considered for thermal decomposition of natural (magnesite, brucite) and synthetic (hydromagnesite, hydroxide) magnesium compounds. Thermophysical properties are established for calcination, effect of heating rate, and temperature on phase composition and amount of heat required for calcination. Coefficients determined are the activation energy and pre-exponential factor in an Arrhenius kinetic equation for decomposition of test minerals. It is established that a more convenient form of magnesium-containing product, obtained as a result of chemical enrichment, is hydromagnesite.
