Boroksit ve üleksit cevherlerinin ferromangan üretiminde kullanımı

Abstract

This study investigated the possibilities of using low-grade manganese ores in ferromanganese production by smelting process. Fluorspar, ulexite, and boroxide (as flux) were added to manganese ores. Fluxes consisting of activated carbon, charge basicity, and charging materials were used in the smelting experiments. Reference samples without flux were also used for comparison. Charge materials were placed in capped graphite crucibles and smelted 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, it was determined that boron ores instead of fluorspar reduced the manganese leakage in the slag to 1% and increased the manganese in the metal phase to 99%. As a result, it was determined that the fluidity of slag increased more than fluorspar and the smelting time decreased, and it is possible to use boron ores in ferromanganese production.
