Tailings crushing sand making process. First, the waste rock chips are sieved, and the particles larger than 5mm (accurately speaking, the upper part of the sieve with a sieve hole length of 4.75mm square hole sieve) are crushed by a vertical shaft impact crusher, which also has a shaping effect and breaks. After the machine is air-separated ...

Tailings pond

 · TAILINGS PONDS 101. Tailings ponds (or tailings storage facilities) play a critical role in storing solids from mined oil sands and managing water flows. These ponds are massive earth structures, initially constructed from overburden hauled from the mine site. Tailings ponds are normally located in a part of the lease that has little or no bitumen.

Tailings

In mining, tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction ( gangue) of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.
