Surface Mining: Aqueous Extraction Methods Flashcards ...
Surface Mining: Aqueous Extraction Methods. 6. As the material disintegrates, the loosened particles (mineral, sand, and gravel) are slurried in water and washed into a sluice., either a natural trough in the ground or a metal or wooden box. 7. The material is then transported by gravity to a riffle box or other more elaborate concentrating device.

Backfill of Tailings to Underground Workings
Tailings can be stored below ground in previous worked out voids. The tailings are generally mixed with a binder, usually cement, and then pumped underground to fill voids and help support an underground mine. For example a 'room and pillar' mining operation that uses backfill will be able to extract the insitu pillars containing ore.
