Bioremediation for Acid Mine Drainage: Organic
Biological sulfate reduction has been slowly replacing chemical unit processes to treat acid mine drainage (AMD). Bioremediations for AMD treatment are favored due to their low capital and maintenance cost. This paper describes the available AMD treatment, current SRB commercialization such as THIOPAQ® and BioSulphide® technologies, and also the factors and limitations faced. THIOPAQ® and BioSu...
متن کاملBioremediation by Sulfate Reducing Bacteria of Acid Mine Drainage
Mining activity produces metal sulfide wastes particularly pyrite which remain in the mine long after operations cease. When water percolates through a mine where oxygen is present, a series of chemical reactions occur which produce extremely low pH and high concentrations of toxic sulfate and metal ions. This toxic leachate can cause severe aquatic habitat degradation downstream of the mine. T...
متن کاملTreatment of Acid Mine Drainage with Sulphate-reducing Bacteria Using a Two- stage Bioremediation Process
Acid mine drainage (AMD) causes several environmental problems in many countries. The use of biological processes with sulphate-reducing bacteria (SRB) has great potential within environmental biotechnology. The aim of this study was to develop a bioremediation system, using a mixed culture of SRB, for the treatment of AMD from São Domingos mine. Sulphate and heavy metals (Fe, Cu and Zn) concen...
متن کاملPrediction of Acid Mine Drainage Generation Potential of A Copper Mine Tailings Using Gene Expression Programming-A Case Study
This work presents a quantitative predicting likely acid mine drainage (AMD) generation process throughout tailing particles resulting from the Sarcheshmeh copper mine in the south of Iran. Indeed, four predictive relationships for the remaining pyrite fraction, remaining chalcopyrite fraction, sulfate concentration, and pH have been suggested by applying the gene expression programming (GEP) a...
متن کاملAcid tolerance of an acid mine drainage bioremediation system based on biological sulfate reduction.
The acid tolerance response of an AMD bioremediation system based on sulfate reduction was investigated. Efficient sulfate reduction was observed with a maximum sulfate reduction rate of 12.3±0.8 mg L(-1) d(-1) and easily available organic carbon was released during high acid treatment with an initial pH of 2.0. The rapid increase in sulfate reduction was observed when the extreme acid treatmen...
