ALGAE-BASED HEAVY METAL REMEDIATION IN ACID MINE DRAINAGE: A REVIEW

Heavy metal removal mechanism of acid mine drainage in wetlands: A critical review

Acid mine drainage (AMD) is one of the most significant environmental challenges facing the mining industry worldwide. Water infiltrating through the metal sulphide minerals, effluents of mineral processing plants and seepage from tailing dams becomes acidic and this acidic nature of the solution allows the metals to be transported in their most soluble form. The conventional treatment technolo...

Metal remediation of acid mine drainage using a hybrid system of microalgae reactor

Acid mine drainage(AMD) contains high concentrations of heavy metals and has become a serious environmental problem. A pipes inserted microalgae reactor(PIMR) was constructed to cultivate microalgae and purify AMD. The effects of metal concentration, pH and sulfate after pretreatment on the removal of iron and microalgae growth were investigated. Batch studies showed that PIMR and microalgae ca...

Bio-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...

THE CENTER FOR A Legislative Agency of the Pennsylvania General Assembly Acid Mine Drainage: Studies in Remediation Acid Mine Drainage: Studies in Remediation Watershed Scale Assessment of an Acid-Mine Drainage Abatement Project in Clarion County

Microbiology of a wetland ecosystem constructed to remediate mine drainage from a heavy metal mine.

A pilot passive treatment plant (PPTP) was constructed to evaluate the potential of a composite wetland system to remediate acidic, metal-rich water draining the former Wheal Jane tin, in Cornwall, England. The treatment plant consists of three separate and controllable composite systems, each of which comprises a series of aerobic wetlands for iron oxidation and precipitation, a compost biorea...
