Abstract
The production of magnesia pellets is developing in mining enterprises, especially in the context of tightening environmental standards and a decrease in sinter production. In the course of the work, it was determined that from the peculiarities of pellet structure formation, the dolomite influence is manifested in a change in both the thermal conditions of firing (the endothermic effect increases with the decomposition of carbonates) and the mineral composition of the fired product. From the point of view of metallurgical properties, MgO contributes to an increase in the strength upon reduction, as well as an increase in carbonates content in the charge leads to an increase in porosity and reducibility. In general, the use of dolomite makes it possible to improve the quality of iron ore pellets by increasing their metallurgical properties.
