摘要：Exploitation on Zn-Pb ores in Upper Silesia region dates back to the XIII century. Analyzed slags are associatedwith Hohenlohe smelting plant which started its work in 1804 as an iron smelter, and continued as zinc smeltersince 1873. Waste material from smelting plant production was stored in Katowice – Wełnowiec, althoughnowadays most of it has been used for commercial purposes. Slags are composed of silicates andaluminosilicates, e.g. willemite, pyroxene- and melilite-group, K-feldspar accompanied by silico-phosphatesclose to perhamite, harrisonite and arsenate-chloride with composition similar to nealite. Chemical compositionof most phases is simple with some unique substitutions in case of Sr and Ce.
