    Tailings Retreatment The Next Revenue Source for the

    Tailings deposited into dams are in the form of a slurry. In 1998, a tailings dam failed at the Los Frailes zinc mine in Spain, causing more than one billion gallons of acidic, heavy metal-laden sludge to spill into the surrounding area, eventually making its way into the Guadiamar River. The spill decimated the area, resulting in massive ...
