Title 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.
