Tailings & Water Management | McLanahan

There are several ways to store tailings following the production process, but the most common method is to pump the tailings slurry to a surface settling pond or impoundment. Settling ponds are large, manmade, relatively calm bodies of water used to store tailings. They allow the suspended solids in a slurry to separate from the liquid.
