Tracing of copper and lead in soils near Kombat mine using stable Cu and Pb isotopes
Original language description
We studied eight soil profiles near the minetailings dams located near the Cu-Pb-(Zn)-Ag mine located at Kombat (Namibia) in order to understand the wind-blown dispersion of tailings-related dust, as well as the subsequent fates of Cu and Pb in a semi-arid soil system. The combination of bulk chemical composition, leaching/extraction tests, and combined Cu and Pb isotope measurements indicated that both metals moved through the soil profiles, but that Pb was more tightly bound to the soil constituents compared to Cu. While the basement rocks yielded negative ?65Cu values, the tailings materials (the major source of contamination in the area) had positive ?65Cu values. Whereas Luvisols were mostly characterized by an increase in Cu concentration with changing ?65Cu value as a function of depth, Chernozems yielded uniform Cu concentrations and isotope compositions in all soil horizons, clearly contrasting with the isotopically lighter composition of the carbonate bedrocks.
