Composition and fate of mine- and smelter-derived particles in soils of humid subtropical and hot semi-arid areas

Popis výsledku v původním jazyce

We studied the heavy mineral fraction, separated from mining- and smelter-affected topsoils, from both a humid subtropical area (Mufulira, Zambian Copperbelt) and a hot semi-arid area (Tsumeb, Namibia). High concentrations of metal(loid)s were detected in the studied soils: up to 1450 mg As kg−1, 8980 mg Cu kg−1, 4640 mg Pb kg−1,2620 mg Zn kg−1. A combination of X-ray diffraction analysis (XRD), scanning electron microscopy (SEM/EDS), and electron probe microanalysis (EPMA) helped to identify the phases forming individualmetal(loid)-bearing particles.Whereas spherical particles originate from the smelting and flue gas cleaning processes, angular particleshave either geogenic origins or they are windblown from the mining operations andminewaste disposal sites. Sulphides from ores andmine tailings often exhibit weathering rims in contrast to smelter-derived high-temperaturesulphides (chalcocite [Cu2S], digenite [Cu9S5], covellite [CuS], non-stoichiometric quenched Cu–Fe–S phases).
