Drainage Waters

Mine drainage waters are widely regarded as environmental pollutants, but they are also potential sources of valuable transition metals, such as zinc, copper and cobalt. This article describes the laboratory application of continuous flow modular bioreactor systems, one oxidative and the other reductive, for the selective precipitation of metals from metal-rich acidic mine waters.

Sorption Characteristics

It was the aim of this work to investigate the sorption characteristics of the Biocer material that consists of cells of Bacillus sphaericus that are immobilised on a ceramic carrier material, performing column experiments with model waters and real mine drainage waters from a U remediation site in East Germany. In column experiments a nearly quantitative sorption of Cu2+ was performed from solutions of different Cu2+ concentrations and at different flow rates. The desorption of the Cu2+ in the columns was nearly quantitative in a very short time. The columns could be regenerated 16 times without a substantial loss of the sorption capacity of the material. In experiments with U using real drainage waters, a specific U sorption capacity of 2.34 mg/g was determined. By variation of the experimental parameters, the long-term stability and sorption properties of the Biocer columns can be substantially improved.
