Low calcining magnesia astringent from brucite rocks

The authors considered the method of stirring up the brucite rocks of calcining process by introducing mineralizer - additions. It is established that leading sodium chloride and magnesium in brucite rock promotes decreasing the temperature of calcining by 200...300 centigrade degrees, thus allow decreasing the power inputs on calcining, solve ecological problems and raise the conditions work quality. Discovered that more active admixture is MgCl26H2O.
