The effect of iron and manganese mine waters on stream biota, Part I: Seasonal and long term trends in mine water geochemistry.

Popis výsledku v původním jazyce

Olší mine (Dolní Rožínka, Czech Republic) was exploited in the years 1958-1989, uranium mineralization is mainly represented by uraninite and coffinite. Uranium mine Olší was closed in 1989. The regulated flooding of the mine continued till autumn 1995 when mine waters reached the surface. During flooding period, the concentration of total dissolved species varied around 650 mg/l, sulphate ions around 200 mg/l, Fe 1 mg/l, Mn 0.2 mg/l, uranium 0.2 mg/l, and 226Ra 50 mBq/l. These concentrations were almost the same as the concentrations characteristic for water in geochemical background. It was assumed that the concentration of TDS and all dissolved species in mine water would gradually decrease during the mine flooding and by the time water reached surface there would be no need to clean or the otherwise process the mine water. It was planned to leak mine water directly to surface into Hadůvka creek. Seasonal and long term trends in natural geochemical evolution of Olší mine water and H
