Estudio de las variaciones mineralógicas y morfológicas en cenizas volantes provocadas por fenómenos de lixiviación
[EN] In this study, three Fly Ashes (FA) from Spanish Power Plants with CaO contents between 2-30% in weight were examined. They were leached using a variation on EPA-EP leaching test, checking the influence of the leaching process on FA. Leaches were analysed by ICP. XRD and SEM-EDX technique were...

| Sumario: | [EN] In this study, three Fly Ashes (FA) from Spanish Power Plants with CaO contents between 2-30% in weight were examined. They were leached using a variation on EPA-EP leaching test, checking the influence of the leaching process on FA. Leaches were analysed by ICP. XRD and SEM-EDX technique were used to analyse the leached FA. The study carried out was mainly centred in following the evolution of the most soluble elements and the formation of new secondary crystalline phases. The relationship between dissolution pH and the percentage of the extracted element was also confirmed. |
