Интенсификация процесса обжига доломита с целью получения активного MgO

Abstract

Active MgO is widely used in various industries, including as an anti-caking material in the technology of mineral fertilizers. The work is devoted to the study of the method of obtaining active magnesium oxide from dolomite rock by separating the temperature range of the processes of decarbonization of magnesium and calcium carbonates. The purpose of the work is to study the effect of the additive of dolomite roasting intensifier in the preparation of active magnesium oxide. Trilon B was used as such an additive. Thermal studies of dolomite and Trilon B mixtures were carried out and the phase composition of the material after calcination at 650 ° C was determined, which showed the effectiveness of the additive and the presence of magnesium oxide while preserving calcite.
