The disclosure relates generally to recovering bond coat materials and barrier coat materials from co-mingled mixtures of bond coat and barrier coat materials (e.g., plasma overspray waste), and from mixtures of co-mingled bond coat and barrier coat materials stripped from a substrate. The disclosure also relates to recovering rare earth elements (e.g., yttrium) from a barrier coat of the co-mingled plasma overspray waste or mixture of co-mingled bond coat and barrier coat materials stripped from the substrate.
