Utilization of coal biomass fly ash in the control and treatment of acid mine drainage
MetadataShow full item record
This study investigated the feasibility of using coal/biomass fly ash (CBFA) blended with various percentages of mine tailings, bentonite, and glacial till soil to control and treat acid mine drainage (AMD). Applications included their use as a cover (cap), liner, low permeability core for dams, and flow-through reactive barriers. These materials were chosen due to their availability and their potential to be a cost effective alternative to traditional technologies and materials.
