1. Phase transformation and surface chemistry of secondary iron minerals formed from acid mine drainage
Abstract : The mining of sulphidic ore to extract metals such as zinc and copper produces huge quantities of waste material. The weathering and oxidation of the waste produces what is commonly known as Acid Mine Drainage (AMD), a dilute sulphuric acid rich in Fe(II) and heavy metals. READ MORE

2. Geochemical Landscape Analysis for the Risk Assessment of Acid Mine Drainage in a Wetland Environment
Abstract : Attenuation of acid mine drainage (AMD) metals originating from abandoned mines and waste rock dumps is investigated in this thesis at Slättberg in central Sweden, where acid mine leachate has been discharging for over 70 years into the receiving wetland stream and mire. Risk assessment of AMD and related polluted lands requires a holistic approach that is able to study the complexity of pollution emissions and impacted landscapes. READ MORE

3. Environmental aspects of coal mine drainage: a regional study of Moatize in Mozambique
Abstract : Mozambique is one of the largest coal producers in Africa. Extraction of the coal is carried out in the Moatize district of the Tete province in the center of the country. A surface mining technique is used to extract the coal below ground level. READ MORE

4. Geochemical modelling of acid mine drainage in mill tailings : Quantification of kinetic processes from laboratory to field scale
Abstract : Assessment of the potentially acidic, heavy metal-ladenleachates that leave deposits of sulfide ore mill tailings andevaluation of various possible options for mill tailingremediation are scientific problems of increasing practicalimportance. High costs may be associated with the mill tailingremediation, not least after recent changes in Swedish andEuropean environmental legislation. READ MORE

5. Potential of fly ashes for neutralisation of acid mine drainage from coal mine waste rock
Abstract : Many countries around the world use coal as fuel for the purpose of power generation. The extraction of coal produces large volumes of waste rock (WR) that are sometimes sulphide rich (principally containing iron sulphides such as pyrite (FeS2) and pyrrhotite (Fe1-xS)), with varying quantities of trace elements such as As, Si, Cu, Zn, Ni, Co, Mo and Cr etc).
