title: Nature and origin of multicomponent aerial emissions of the copper-nickel smelter complex.
abstract: The Severonickel Smelter Complex as well as other big nickel-copper smelter plants are the source of metallurgical dust emissions, enriched with toxic elements Ni, Cu, Pb, Zn and As. The phase composition of typical metallurgy dust is described as pentlandite (Ni,Fe)9S8, pyrrhotite Fe7S8(Ni(x)), chalcopyrite CuFeS2, chalcosite Cu2S, covellite CuS, cuprite Cu2O, tenorite CuO, and metal copper and nickel. The fine dust fractions are enriched by lead, zinc and arsenic oxides. The obtained data can be turned to account when conducting the investigations of heavy metal behaviour in nature media, in particular soils.
