Passive Treatment of Acid-Mine Drainage
Introduction Acidic mine drainage (AMD; also called “acid rock drainage” or “acid drainage”) is an environmental pollutant that impairs water resources in mining regions throughout the world. Where such treatment is required legally, treatment must be efficient and continual. Treatment methods are commonly divided into either “active,” meaning reliance on the addition of alkaline chemicals to n...
متن کاملHeavy 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...
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...
متن کاملMagnetic Nano mineral and acid mine drainage interaction: An experimental study
In the environment, two main sources of heavy metals are natural backgrounds derived from parent rocks and anthropogenic contamination including mineral industrial wastes, tailing damps of sulfide mines, agrochemicals, and other outputs of industrial activities and factories. In this work, the physico-chemical aspects of the magnetic Nano- mineral surfaces are studied in contrast to acid mine d...
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...
