- Abstract
The unexploited potential of ashes, especially from lignite combustion in power plants, for the strategic recovery of secondary resources requires a sufficient, substantial and reliable analysis. Thus, information facilitates pathways to dedicated metal extractions and optimized recovery strategies. Based on two fly ashes and a stabilized form, delivered from Lusatia, the characterization, concerning the particle size distribution, elemental and mineralogical composition and the ratio of network former to modifier, led to a significant increase in the mobilization of metals by the leaching of the educts with hydrochloric acid.
