Abstract

The most important physicochemical parameters of several selected carbons from Polish coal beds in the context of using them as a material in ferrosilicon smelting process were analysed in this paper. Among coals presented in the paper, coal from Wujek Coal Mine has been used as a main reducer in the Polish ferroalloy industry until recently, but its resources have run out. Currently, coals from Staszic Coal Mine and Wieczorek Coal Mine are used as the main reducers for ferrosilicon smelting process. Coals from Bogdanka, Piast and Ziemowit Coal Mines are indicated to be potential substitutes of reducers for the ferrosilicon smelting process. Basic parameters of carbon, obtained using technical and elementary analysis, the chemical composition of ash as well as results of research on vitrinite reflectance and reactivity towards SiO and CO2, have been compared in this paper.
