Summary:The research presents the calculations of the analytical expressions of the oxide system MnO-CaO-Al2O3-SiO2 and the phase compositions of the slags from the production of refined ferromanganese. It is determined that the system under consideration is divided into 19 elementary quasi-systems consisting of incongruently melting and congruently melting compounds. The sum of the relative volumes of the elementary tetrahedron of the MnO-CaOAl2O3-SiO2 system equals one (1,000000), which confirms the accuracy of the performed calculations. Quasi-volumes in the system MnO-CaO-Al2O3-SiO2, simulating the composition of the resulting slag in the process of metallothermic recovery of manganese concentrates are found.
