Gallium and germanium in metallurgical slags: mineralogy and potential recovery

Autor: Vojtech Ettler, Martin Mihaljevic, Radim Jedlicka, Bohdan Kribek, Ben Mapani, Fred Kamona, Rob J. Bowell, Tomas Hrstka

Gallium (Ga) and germanium (Ge) are technologically essential critical elements. This study focuses on old metallurgical slags generated by processing non-ferrous metallic ores in Tsumeb, northern Namibia, containing interestingly high concentrations

Thallium and lead variations in a contaminated peatland: An isotopic study from a mining/smelting area

Autor: Ales Vanek, Katerina Vejvodova, Martin Mihaljevic, Vojtech Ettler, Vit Penizek, Jakub Trubac, Katarzyna Sutkowska, Leslaw Teper, Viktor Golias, Maria Vankova

Vertical profiles of Tl, Pb and Zn concentrations and Tl and Pb isotopic ratios in a contaminated peatland/fen (Wolbrom, Poland) were studied to address questions regarding (i) potential long-term immobility of Tl in a peat profile, and (ii) a possib

Stable thallium isotope fractionation in soils as affected by pedogenesis

Autor: Vojtech Ettler, Lenka Pavlu, Andreas Voegelin, Tereza Zádorová, Maria Vankova, Martin Mihaljevič, Petra Vokurková, Jakub Trubač, Ondrej Holubik, Ales Vanek, Vit Penizek, Vendula Oborná, Ondrej Drabek, Petr Drahota

In this study, we investigated if variations in the stable Tl isotope ratios in soil samples from different profiles can be linked to data on the extractability and speciation of soil Tl and whether the isotopic data allow drawing conclusions on the

Historial thallium deposition trends as recorded in peat bogs - examples from Czech sites with contrasting pollution histories

Autor: Martin Mihaljevič, Ales Vanek, Vojtech Ettler

The purpose of this study is to investigate the Tl distribution and accumulation rates in Czech peatbogs with contrasting anthropogenic loads. Nine peat cores were sampled in the mountain areas of the Czech Republic (6 cores in the northern part affe

Mineralogy and environmental stability of vanadium-rich slags from the historical processing of Zn-Pb-V ores at Berg Aukas (Namibia)

Autor: Vojtech Ettler, Martin Mihaljevic, Alice Jarosikova, Adam Culka, Bohdan Kribek, Ales Vanek, Vit Penizek, Ondra Sracek, Ben Mapani, Fred Kamona

Vanadium (V) is one of the key technologically critical elements. The slags produced by the historical mining and processing of Zn–Pb–V ores in the Waelz kiln at Berg Aukas (northern Namibia) can be potentially used as a secondary resource of V.
