Uranium attenuation from tailing waters by floating macrophyte Lemna gibba L.
Biosorption of uranium from mine tailing waters by floating macrophyte Lemna gibba L. was investigated in nutrition solutions. Changes in pH (from...
-
Mine Water
Water is needed at mine sites for dust suppression, mineral processing, coal washing, and hydrometallurgical extraction. For these applications,...

Seasonal changes in the microbial community of a salt marsh, measured by phospholipid fatty acid analysis
Microbial activity within the environment can have distinct geochemicaleffects, and so changes in a microbial community structure can result...

Retention of Radionuclides and Arsenic by Algae Downstream of U mining Tailings
Algae including cyanobacteria function as efficient temporary sinks in wetlands below uranium mining tailings and dumps. As far as investigated their...
-
Microbially mediated reduction and immobilization of uranium in groundwater
Aquifers near uranium mines are frequently contaminated with uranium and other metals. Under certain conditions, indigenous microbes can be used to...
-
Characterization of uranium (VI) complexes formed by different bacteria relevant to uranium mining waste piles
A combination of Extended X-ray Absorption Fine Structure (EXAFS) spectroscopy and Infrared (IR) spectroscopy was used to characterize the uranium...
-
Microbial Transformations of Uranium Complexed with Organic and Inorganic Ligands
Biotransformation of various chemical forms of uranium present in wastes, contaminated soils and materials by microorganisms under different process...
-
Bacterial-based bioremediation of uranium mining waste waters by using sol-gel ceramics
Cells, spores and the surface layer protein (S-layer) of the Bacillus sphaericus strain JG-A12, recovered from a uranium mining waste pile, were...

Ecological water treatment processes for underground uranium mine water: Progress after three years of operating a constructed wetland
Sustainable treatment approaches are sought for U mine waste water u-tilizing constructed wetlands. In 1998 a pilot system was constructed to remove...

Removal of acid violet from wastewater by adsorption on waste red mud
Waste red mud obtained during the processing of bauxite ore has been used for the adsorption of acid violet at different initial dye concentrations...

Active Treatment of Polluted Mine Waters
Before about 1980 (e.g. Barton, 1978), the only proven technologies for mine water treatment were those which we now term “active treatment”. Active...

The Use of Immobilised Rhizopus oryzae as a Biosorbent for Reactive Dye and Metal Ions
Rhizopus oryzae can biosorb reactive dye, copper, and cadmium ions from aqueous solution. This paper investigates the possibility of...
-
Adsorption of copper and zinc by oil shale
Oil shale is able to remove appreciable amounts of copper and zinc ions from aqueous solutions. It was noted that an increase in the adsorbent...
-
A review of heavy metal adsorption by marine algae
Accumulation of heavy metals by algae had been studied extensively for biomonitoring or bioremediation purposes. Having the advantages of low cost...

Chemical composition and leaching characteristics of granules made of wood ash and dolomite
In 1995, the central heating plant Draken in Kalmar, Sweden, started manufacturing a granular ash product for nutrient recycling to forest soil,...

Sorption on Humic Acids as a Basis for the Mechanism of Primary Accumulation of Gold and Platinum Group Elements in Black Shales
In order to asses the contribution of sorption by complexation to the concentration of noble metals at early stages of the formation of their...
