Bioleaching of cobalt from Cu/Co-rich sulfidic mine ...

2020-11-1  Abstract. A microbial consortium of mesophilic and acidophilic bacteria and archaea was applied in shake flasks as well as in 2 L stirred tank reactors (STR) to bioleach cobalt, copper, and other valuable metals from sulfidic mine tailings (Rammelsberg polymetallic massive sulfide deposit, Harz Mountains, Germany).

2015-4-1  These sulfide minerals are mainly separated from iron oxides by a reverse flotation process in which a low grade copper–nickel–cobalt bearing material is produced as the floated portion. Unpublished preliminary investigations showed that this tailing could not be upgraded by conventional physical or physicochemical methods.
