The paper presents the results of a study of the mineralogy of copper slags from the old Lyalinsky plant, which operated in 1724-1779 in the vicinity of the village of Karaul (now Karaulskoye). The plant was founded by General V.I. de Gennin and became the first state-owned copper smelter in the Northern Urals. The plant smelted ores from the Lyalinsky, Pavdinsky and Konzhakovsky mines. Our studies have established that the copper slags are composed of pyroxene (diopside, hedenbergite) with the constant presence of plagioclase (anorthite), as well as kirsteinite, fayalite, glass, hercynite, troilite and copper-iron sulfides (bornite and “melt solid solutions”). In addition, copper with a high admixture of silver and cohenite were found. Of the secondary miner-als, malachite, cuprite, chrysocolla and chalcosiderite have been identified. The presence of sulphides in the copper slags of the Lyalinsky plant indicates that copper pyrites from the Serebryansky stone mines were used as ore during smelting. The slags can be processed with the release of sulphide concentrate with valuable met-als, and the remaining aluminosilicate mass can be used as raw material for the production of heat and sound insulating basalt wool.
