The Passive Treatment of Arsenic-containing Acid Mine Drainage and Using Manganese-coated Bone Char and Evaluation on its Neutralization Ability
نویسندگان
چکیده
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 coated layer could reduce the neutralization ability of bone char. The comprehensive performances of adopting manganese-coated bone char to remediate AMD should be comprehensively evaluated based on the removal and neutralization effectiveness.

Identification of the Origin and Behaviour of Arsenic in Mine Waste Dumps Using Correlation Analysis: A Case Study Sarcheshmeh Copper Mine
Knowledge of the probable origin and behaviour of arsenic certainly gives valuable insights into the potential for transfer in the environment and of the risks involved in mining sites. Sequential extraction analyses are common experiments often used to study the origin and behaviour of potentially toxic elements. The method, however, presents some deficiencies, including labor-intensive proced...

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...

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 کاملConversion of coal mine drainage ochre to water treatment reagent: Production, characterisation and application for P and Zn removal.
Coal mine drainage ochre is a ferruginous precipitate that forms from mine water in impacted watercourses and during treatment. With thousands of tonnes per annum of such ochre arising from mine water treatment in the UK alone, management of these wastes is a substantive issue. This paper demonstrates that the ochre from both active and passive treatment of coal mine drainage can be transformed...

The oxidation of sulfide minerals in coal and mine's waste materials produce acid mine drainage. The evaporation, oxidation, dilution and neutralization of this acid drainage lead to formation of secondary minerals. Due to having broad surface spreading these minerals have the potential of maintaining sulfates and many of the metallic elements. In order to carry out mineralogical and geochemica...
