Abstract

The phase characteristics of calcite "limestone"-marble from Banjany area village (near Skopje, Macedonia) were examined by means of XRD, SEM microscope in polarizing and reflected lights, chemical, DT/TG-analyses. It was concluded as follows: - calcite (CaCO3) is a major mineral component (cca 80-90 %) prevailing in the marble over the other minerals - dolomite is generally of minor importance (cca 10-20 %) in the rock - quartz, micas graphite, pyrite represent typical accessories. As result of the mentioned phase characteristics, this raw materials was for a long time (more than 30 years) used as flux in the iron and steel metallurgy in Macedonia.
