| Abstract: | The chemical state of gold in gold ores, mattes and roaster products has been studied by197Au Mössbauer spectroscopy. Gold minerals were studied in order to provide reference data for the ore spectra.57Fe Mössbauer spectroscopy was used to monitor the iron compounds always present in gold ores and to follow their transformations caused by smelting and roasting. |
