Microbial Communities Inhabiting a Rare Earth Element Enriched Birnessite-Type Manganese Deposit in the Ytterby Mine, Sweden

Microbially mediated formation of birnessite - type manganese oxides and subsequent incorporation of rare earth elements , Ytterby mine , Sweden

Microbes exert extensive control on redox element cycles. They participate directly or indirectly in the concentration and fractionation of elements by influencing the partitioning between soluble and insoluble species. Putative microbially mediated manganese (Mn) oxides of the birnessite-type, enriched in rare earth elements (REE) + yttrium (Y) were recently found in the Ytterby mine, Sweden. ...

REE-Enriched Mn-Oxide Precipitates in Water-Bearing Fractures in the Ytterby Mine, Sweden

The Ytterby mine, Sweden, is known for the discovery of eight elements, including yttrium and five of the rare earth elements (REE). The mine was in operation from 1750 to 1933 and was after closure used as a storage depot for fuel from the 1950s to 1995. A tunnel was opened in the 1950s through the bedrock into the mine to allow access to the storage depot. Recent water monitoring campaigns (2...

Microbial communities in acid mine drainage.

The dissolution of sulfide minerals such as pyrite (FeS2), arsenopyrite (FeAsS), chalcopyrite (CuFeS2), sphalerite (ZnS), and marcasite (FeS2) yields hot, sulfuric acid-rich solutions that contain high concentrations of toxic metals. In locations where access of oxidants to sulfide mineral surfaces is increased by mining, the resulting acid mine drainage (AMD) may contaminate surrounding ecosys...
