Abstract
This study develops a valley-wide mill tailings disposal plan to utilize 20 potential landfill sites on floodplain areas in the Coeur d`Alene Mining District in Idaho, and presents measures to reclaim the sites for subsequent productive use. Field and laboratory testing on one test section and two abandoned impoundments support the use of hydraulically deposited tailings for landfill construction. Hydrological testing showed that controlled discharge from tailings impoundments results in contaminant levels in the discharge below regulated standards. Additional testing indicated that compacted soil liners and pond management provide adequate contaminant abatement where acid-generating tailings are encountered. Mechanical compaction, including surcharge loading, upgrades foundation support capacity so that construction on the surface of tailings deposits is feasible. At recent production rates, the 20 sites would result in 680 acres of reclaimed land while providing a minimum of 40 years of tailings storage capacity.
