Biological manganese removal from acid mine drainage in constructed wetlands and prototype bioreactors.
Mine drainage waters vary considerably in the range and concentration of heavy metals they contain. Besides iron, manganese is frequently present at elevated concentrations in waters draining both coal and metal mines. Passive treatment systems (aerobic wetlands and compost bioreactors) are designed to remove iron by biologically induced oxidation/precipitation. Manganese, however, is problemat...
متن کاملThe Passive Treatment of Arsenic-containing Acid Mine Drainage and Using Manganese-coated Bone Char and Evaluation on its Neutralization Ability
The technologies of treating acid mine drainage (AMD) commonly include active and passive treatment. The coating technology can enhance the removal performance of some low-cost adsorbents. This study adopted Langmuir and Freundlich isotherm to fit the batch experimental dates. The results show that the Qmax of coated bone char could increase 78.83 times than uncoated bone char. However, the coa...
متن کاملPreventing acid mine drainage from mine tailings
Mining activity always has high impact on its surroundings, being waste deposition the cause of multiple and complex problems to the environment. One of them is Acid Mine Drainage (AMD), causing acid water percolation through large areas in the mine site. Portugal was a prosper tungsten producer from the beginning of the XX century, having its apogee during World War II. Nowadays there are mill...
متن کاملRemoval of Copper Ions from Acid Mine Drainage Wastewater Using Ion Exchange Technique: Factorial Design Analysis
A factorial experimental design method was used to examine the “Cu” removal from acid mine drainage wastewater by ion exchange technique. Ion Exchange technique is preferred because of reduced sludge generation compared to conventional treatment techniques and better decontamination efficiency from highly diluted solutions. Factorial design of experiments is employed to study the effect of four...
متن کاملBio-Remediation of Acid Mine Drainage in the Sarcheshmeh Porphyry Copper Mine by Fungi: Batch and Fixed Bed Process
Acid mine drainage (AMD) containing high concentrations of iron and sulphate, low pH and variableconcentrations of heavy metals leads to many environmental problems. The concentrations of Cu and Mnare high in the AMD of the Sarcheshmeh porphyry copper mine, Kerman province, south of Iran. In thisstudy, the bio-remediation of Cu and Mn ions from acid mine drainage was investigated using two nati...
