dc.description.abstractA pilot scale, silicomanganese alloy production campaign was performed in a 440 kVA, single phase electric furnace in order to establish an overview of the minor- and trace element contents in process input raw materials and their distribution in the resulting primary and secondary products. Samples of the in-going raw materials (manganese ore, coke, quartzite, and high carbon ferromanganese slag) and the out-going products (silicomanganese alloy, silicomanganese slag, and dust) were analyzed by inductively coupled plasma mass spectrometry. The distribution of 51 elements between the product phases was discussed in terms of their boiling temperatures, Gibbs energies of oxidation and activity coefficients of elements in the metal. A thermochemical simulation using the thermochemical software FactSage 7.1 was also carried out in order to model element phase distribution between the alloy, slag, and dust/gas. The correlation between the model and experimental element concentrations in the silicomanganese slag and dust is fair for most elements. However, in the metal phase, fewer elements show good correlation between modeled results and measured experimental concentrations. The discrepancy could be explained by a lack of accurate thermodynamic descriptions for several minor species in the database.nb_NO
