Upper Silesia District is one of the most polluted areas in the country. Rich deposits of metal ores and hard coal have contributed to the extensive development of metallurgy and mine industry which started as early as in the Middle Ages. The ecological hazard can be illustrated by an over 100-year-old waste dump of Zn-Pb ores in one of the Silesian cities – in Ruda Śląska. Despite the long storage period, the wastes, represented mainly by weathered slags as also vitrified waste material, contain of lot of heavy metals in varied their chemical forms. The following metals have been found in wastes: Cd, Pb, Zn, As, Cu, Ti and other, and also a lot of amounts of iron. In the article the results Mössbauer spectroscopy are presented, as a preliminary stage of mineralogical studies of Zn-Pb wastes. Depending on the type of tested waste material different iron phases have been shown: in the weathered slag four different products of the iron oxidation were detected: divalent Fe(OH)₂, mixed valence magnetite, Fe₃O₄ and three valence Fe(OH)₃, α Fe₂O₃ and γ-Fe₂O₃ compounds, in the vitrified material metallic forms of iron are dominated.
