Integrated acid mine drainage management using fly ash.
Fly Ash (FA) from a power station in South Africa was investigated to neutralise and remove contaminants from Acid Mine Drainage (AMD). After this primary treatment the insoluble FA residue namely solid residue (SR) was investigated as a suitable mine backfill material by means of strength testing. Moreover, SR was used to synthesise zeolite-P using a two-step synthesis procedure. Furthermore, ...
متن کاملRecovery of Metals from Acid Mine Drainage
Acid Mine Drainage (AMD) poses a severe pollution problem attributed to current and past mining activities. Low pH, high concentrations of sulphates and various heavy metals makes AMD treatment a major concern because of possible deleterious effects of the effluent on the surroundings. Treatment methods to address AMD focus on neutralizing, stabilizing and removing problem pollutants through va...
متن کاملMineralogy and Trace Element Partitioning in Coal Fly Ash/Acid Mine Drainage Co-Disposed Solid Residues
Acid mine drainage (AMD) was reacted with coal fly ash in a 24 hour equilibration time using 3:1 and 1.5:1 AMD: FA ratios by weight to produce neutral and alkaline process waters and remove major and minor elements from solution. The elemental concentration trends with time in the solution were used to discern which elements have solubility control in the neutralization process. The resulting c...

متن کاملHeavy metals from acid mine drainage - impacts and modelling strategies
Mine drainage is increasingly becoming a problem in the UK as water tables rise and acid drainage waters rich in heavy metals impact river systems. The impacts of mine drainage at two sites, the River Pelenna in Wales and the Wheal Jane Mine in Cornwall is assessed. Mathematical models have been developed and applied to investigate heavy metal pollution in the Pelenna case study and the models ...
