Abstract
The possibility of on-line membrane size-fractionation of water compon ents and simultaneous separation of particulate and dissolved matter a t each filtration stage has been shown. The distribution patterns have been studied for As, Fe and Mn in effluent samples of tin ore tailing s (Altenberg, Saxony, Germany). The seepage composition is characteriz ed by high concentrations of Fe and As. The particulate and dissolved components were separated in five fractions between 0.025 and 8 mu m. It was suggested that the distribution patterns of As and Fe compounds depend on the chemical conditions at the sampling sites. Manganese ex ists mainly in solvated forms in the liquid fractions.
