New Technologies on Mine Process Tailing Disposal
The analysis indicated that the unit costs of the tailing dam, the surface disposal method, and the geotextile method were calculated as 2.25 $/ton, 2.29 $/ton, and 7.39 $/ton, respectively. However, the unit price of surface paste disposal method become 2.79 $/ton when cement was used.

Case Summary: Settlement Clears Way for Purchase and Cleanup of Mine
The Site contains three very large tailings piles that are being actively eroded by three different streams (Sneffels Creek and Imogene Creek enter the Site and combine in the middle of the tailings to form Canyon Creek). All three tailings piles are also susceptible to flood events, increased runoff and failure of the existing slopes.
