The silver ore, anode mud, chimney power, concentrator sample and waste damp samples obtained from the Gumuskoy Silver Plant have been analyzed for their elemental constituents. The prepared samples were analyzed using a polarized energy dispersive X-ray fluorescence (PEDXRF) spectrometer. The result of the analysis shows the presence of many elements including rare earth elements (from Na to Th). The accuracy and precision of the technique for chemical analysis is demonstrated by analyzing USGS standards, GEOL, SILVER, K07-CoO Cobalt oxide, GBW 7109 Ijolite Sy and GBW-7309 Sediment.
