  Title (up) Designing wetlands for controlling coal mine drainage: an ecologic- economic modelling approach Type Journal Article
  Year 1991 Publication Ecological Economics Abbreviated Journal  
  Volume 3 Issue 1 Pages 1-24  
  Keywords mine drainage economic cost iron removal simulation model ecotechnology modelling approach treatment efficiency wetland design wastewater treatment USA Alabama USA Tennessee USA Ohio  
  Abstract A simulation model is developed of the efficiency and economics of an application of ecotechnology – using a created wetland to receive and treat coal mine drainage. The model examines the role of loading rates of iron on treatment efficiencies and the economic costs of wetland versus conventional treatment of mine drainage. It is calibrated with data from an Ohio wetland site and verified from multi-site data from Tennessee and Alabama. The model predicts that iron removal is closely tied to loading rates and that the cost of wetland treatment is less than that of conventional for iron loading rates of approximately 20-25 g Fe m “SUP -2” day “SUP -1” and removal efficiencies less than 85%. A wetland to achieve these conditions would cost approximately US$50 000 per year according to the model. When higher loading rates exist and higher efficiencies are needed, wetland systems are more costly than conventional treatment. -Authors

  Title (up) Injection of Fluidized Bed Combustion Ash into Mine Workings for Treatment of Acid Mine Drainage Type Journal Article
  Year 2006 Publication Mine Water Env. Abbreviated Journal  
  Volume 25 Issue 1 Pages 45-55  
  Keywords acid mine drainage AMD alkaline injection technology fluidized bed combustion ash Oklahoma  
  Abstract A demonstration project was conducted to investigate treating acid mine water by alkaline injection technology (AIT). A total of 379 t of alkaline coal combustion byproduct was injected into in an eastern Oklahoma drift coal mine. AIT increased the pH and alkalinity, and reduced acidity and metal loading. Although large improvements in water quality were only observed for 15 months before the effluent water chemistry appeared to approach pre-injection conditions, a review of the data four years after injection identified statistically significant changes in the mine discharge compared to pre-injection conditions. Decreases in acidity (23%), iron (18%), and aluminium (47%) were observed, while an increase in pH (0.35 units) was noted. Presumably, the mine environment reached quasi-equilibrium with the alkalinity introduced to the system.

  Title (up) Neutral mine drainage Type Book Chapter
  Year 1999 Publication Sudbury '99; mining and the environment II; Conference proceedings Abbreviated Journal  
  Volume Issue Pages  
  Keywords acid mine drainage drainage geochemistry mining mining geology models neutral mine drainage pH pollution remediation technology water management water quality water resources 22, Environmental geology  
  Abstract Acid mine drainage is recognized as a serious environmental issue at mine sites world wide. While sulphate and metal concentrations in acidic drainage can reach exceptionally high levels, these can also be elevated and of concern in neutral drainage from waste rock and tailings. “Neutral mine drainage” (NMD) has not yet received as widespread attention as acid mine drainage (AMD). The oxidation of sulphide minerals and the production of either acidic or neutral contaminated drainage is affected by many factors. This paper examines the specific factors that result in the production of “neutral mine drainage” from mine wastes. Several case studies are presented which involve predictive geochemical modelling to illustrate the possible time frame and magnitude of contaminated neutral drainage.
