STUDY OF THE CHEMICAL AND MINERAL COMPOSITION OF DOLOMITE.

The dolomite of the Djamansai deposit of the Republic of Karakalpakstan (Uzbekistan) has been studied. It was found that the dolomite ore of the Djamansai deposit contains a minimum amount of impurities and a sufficient magnesium content. The temperature intervals of the two stages of dolomite dissociation, as well as the temperatures at which the dissociation rate is maximal, are determined. It is shown that dolomite is suitable for the production of magnesia binding systems.
