    摘要: A process for remediation of impounded coal ash comprises removing the coal ash as a slurry from a storage pond. The slurry is subjected to a separation treatment in which fines are separated from coarser material present in the slurry. The separated fines are passed to a flotation stage in which unbumt carbon and organic matter (when present) are separated from the fines. An underflow of the flotation stage comprising the fines is passed to a metals extraction stage wherein metal contaminants that are present in the fines underflow are removed, and a fines stream is produced that is substantially free of such metals. The metals-free fines stream is dewatered to produce a first fine ash product. The process can also produce: a granular fill material product, a finer ash product and an aggregated product.

    摘要: A multifunctional comprehensive mineral supplement containing one or more molecular clusters, wherein each of the one or more molecular clusters has a metal-containing core and one or more ligands attached to the metal-containing core, wherein at least a portion of the metal-containing core and/or the one or more ligands is derived from a mineral component, wherein the mineral component is obtained from at least one mineral source, and wherein the at least one mineral source includes at least one selected from the group consisting of bauxite residue, ultrabasic rock, and a combination thereof.
