Abstract :This study investigated the possibilities of using low-grade manganese ores in ferromanganese production by smelting process. It is aimed to increase the consumption areas of boron ores. Fluorspar, ulexite, and boroxide were added to manganese ores, and slag fluidity at determined temperatures was examined. Reference samples without flux were used for comparison. The charge materials were melted in graphite crucibles at 1650 °C for 2 hours. The metal/slag phases were separated from each other and their chemical analyses were made. At the end of the experiments, thanks to boron ores, Mn leakage in the slag phase was reduced to a minimum, while 99% Mn was obtained in the metal phase. As a result, it has been determined that the slag fluidity increases more with boron ores (compared to fluorspar), the smelting time decreases, it is possible to use boron ores in ferromanganese production, and their usage areas can be increased.Keywords : Ferromanganez, Üleksit, B2O3, CaF2, Ergitme, Manganez
