Abstract

In order to determinate the best conditions to obtain magnesite as raw material in the leaching with carbonic acid processes for magnesium contend dissolution, in this paper, its study thermal treatment on sample of magnesite from ¨Magnesita Redención¨ deposit in the Minas region of Camagüey province.The calcinations experiment with the helping of analytical technique like Differential Thermical-Thermogravimetric Analysis (DTA-TG) and Ray X Diffraction (DRX) were done in order to determinate the composition of mineralogical phases with are formed during the thermal treatment as well as the best conditions to obtain maxim magnesium dissolution on leaching. Also, it was determinate the theory soluble magnesium since chemical and phase composition. The best results are between temperature ranges from 775 to 800 0C in which magnesium contended on treated product was from 53,88 to 54,38 % ( form a possible maxim of 54,88 %, that correspond to the maxim lost of weigh =38,6 %), because of in that conditions magnesite are totally decomposed (MgCO3) y el MgCO3 from dolomite.
