Development of Methods for Reclaiming Tailings Ponds and Dams. Volume I.
NTIS: PB/82-195736 :34 pages
This report describes methods of reclaiming abandoned or inactive tailings ponds and dams. The investigated sites were selected tailings deposits adjacent to metal mines in the southwestern United States and the Pacific Northwest. The basic data developed for each site consisted of a review of existing literature, a site visit that included sampling of the tailings and surrounding materials, laboratory and engineering studies, and development of reclamation plans. Laboratory tests determined the gold and silver content of each deposit and the chemistry of the tailings and surrounding materials. Reclamation plans that include approximate costs were developed for five deposit sites ranging from 52,000 to 103 million tons. Conclusions on the remaining potential of each site are based on the tailings assay and other technical data. This study concludes that remaining as a reclamation tool is feasible at certain sites.
