Abstract We studied the dust fractions of the smelting slag, mine tailings, and soil from the former Ni‐Cu mining and processing district in Selebi‐Phikwe (eastern Botswana). Multi‐method chemical and mineralogical investigations were combined

Oral bioaccessibility of metal(loid)s in dust materials from mining areas of northern Namibia

Autor: Vojtěch Ettler, Markéta Cihlová, Alice Jarošíková, Martin Mihaljevič, Petr Drahota, Bohdan Kříbek, Aleš Vaněk, Vít Penížek, Ondra Sracek, Mariana Klementová, Zbyněk Engel, Fred Kamona, Ben Mapani

Publikováno v: Environment International, Vol 124, Iss , Pp 205-215 (2019)

Ore mining and processing in semi-arid areas is responsible for the generation of metal(loid)-containing dust, which is easily transported by wind to the surrounding environment. To assess the human exposure to dust-derived metal(loid)s (As, Cd, Cu,

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

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.

Barite-hyalophane sulfidic ores at Rozna, Bohemian Massif, Czech Republic; metamorphosed black shale-hosted submarine exhalative mineralization

Autor: Bohdan Kribek, Zbysek Uhlik, Jana Hladíková, Marta Pudilová, Jiri Bendl, Karel Zak

Publikováno v: Economic Geology. 91:14-35

Strata-bound barite-hyalophane sulfidic orebodies recently discovered at Rozna (in the Moldanubian zone of the Bohemian Massif, Czech Republic) are hosted within the high-grade metamorphosed complex composed of migmatitic biotite or sillimanite-bioti

The role of organic matter in the metallogeny of the Bohemian Massif

Autor: Bohdan Kribek

Publikováno v: Economic Geology. 84:1525-1540

Formations rich in organic matter occurred throughout most of the geologic history of the Bohemian Massif. Accumulation of organic matter was connected with basic submarine volcanic activity, with transgressive sedimentary regimes, and with limnic an
