stream of process-tailings (in slurry form) will be discharged to an In-Pit-Tailings-Storage Facility (IPTSF) at the Rav8 Mine. The IPTSF will comprise both the Rav8 underground-workings, and the Rav8 Pit. It is proposed to initially discharge process-tailings into the underground-workings, so that the majority of the void-spaces are filled.

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.

Mine tailings can be classified as slurry, paste, or cake, according to its final solid/liquid ratio (S:L), which arises from the treatment given to the slurries at the end of the extraction process. Slurry undergoes no treatment, paste is a thickened slurry, and cake is a filtered slurry (see Fig. 1).

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 ...
