    Ocena i wykorzystanie warunków środowiskowych w procesie wzbogacania kopaliny na drodze (bio)hydrometalurgicznej

    These are results of research on the possibility of enrichment uranium-bearing shales (black shales and walchia shales), which at a comparable, trace level of metal-bearing were strongly differed in their geochemical environments, which developed as a result of different compositions of microflora. Research was carried out on the dynamics of growth of micro-organisms most frequently represented in each of the geochemical environments and the associated with varying effectiveness of the leaching. It demonstrated that the enrichment of two radically different raw-shale materials using the biotechnical methods is possible, if taking into account every time changeable, individual and particular method, using the natural biogeochemical conditions of the raw material.
