TL;DR: Efficiency of the elements removal was directly linked to the amount of FA in the reaction mixture and to the final pH attained, and significant leaching of B, Sr, Ba and Mo was observed as the reaction progressed and was observed to increase with quantity of fly ash in the Reaction mixture.

TL;DR: In this paper, the capacity of fly ash to remove the major inorganic contaminants was examined and the elemental concentration trends with time for the two ratios were used to determine which elements have solubility control in the neutralization process.

TL;DR: In this article, a column leaching study of the solid residues blended with varying amounts of fly ash (5, 25, 40%) and 6% ordinary portland cement (OPC) and fresh fly ash was carried out to assess the neutralisation and contaminants attenuation in AMD with time.

TL;DR: XRF analysis was used to determine Si and Al in fly ash (FA) precipitates and predict whether the fly ash precipitates could successfully be converted to faujasite zeolitic material by the synthetic method.

TL;DR: A co-disposal reaction was used wherein fly ash (FA) was reacted with acid mine drainage (AMD), to collect filtrates for zeolite synthesis as discussed by the authors, which were then analyzed by XRF spectrometry for quantitative determination of SiO2 and Al2O3.
