Recovery of metals from coal ash: an annotated bibliography. [243 items with abstracts]

The criteria upon which the citations were chosen for this review were: (1) the citation had to mention coal ash as one of the raw materials or potential raw materials; and (2) the citation had to be concerned with the recovery of metals, or of minerals from which metals could be produced. Not included, for example, were citations which covered the general topic of recovery of Al from non-bauxite sources or the recovery of metals from flue gas desulfurization sludge. Also citations were excluded which covered the use of coal ash as an additive to concrete, a raw material for cement manufacture, a source of synthetic aggregate, or generally related to construction. In addition to this primary search of the literature, an overall secondary search was conducted through the references cited in the English language papers obtained in the primary search. The citations obtained in this secondary search were again judged on the above criteria for inclusion in this review. A final list of 244 citations formed the bibliography. Annotations for these citations were prepared from the papers themselves, if possible, or from abstracts of the papers. A few pertinent citations were included where neither the paper nor an abstractmore » was available. The bibliographic citations and annotations appear in Section 7.0 of this review. A cross-index of the bibliographic citations is given in Section 6.0.« less
