Oxidation of the arsenic-rich concentrate at the Přebuz abandoned mine (Erzgebirge Mts., CZ): mineralogical evolution

Ore concentrate with up to 65 wt.% of arsenic (by-product of cassiterite extraction) exposed to climatic conditions was studied from the mineralogical point of view. Detailed sampling, X-ray diffraction analyses, energy-dispersive microanalysis (EDAX) and especially scanning electron microscopy (SEM...

Description
Summary:Ore concentrate with up to 65 wt.% of arsenic (by-product of cassiterite extraction) exposed to climatic conditions was studied from the mineralogical point of view. Detailed sampling, X-ray diffraction analyses, energy-dispersive microanalysis (EDAX) and especially scanning electron microscopy (SEM) were applied to study the arsenopyrite–löllingite-concentrate weathering. The studied concentrate contains very small proportion (
