Most mines use a series of small settling ponds to permit more flexible water management. Small ponds are usually easier to build, repair, dean, replace, bypass, and rehabilitate than larger ponds. The use of pre-settling ponds is encouraged. A pre-settling pond is located in the tail race between the sluice and the first settling pond.

Tailings Ponds 101 Oil Sands Magazine

Feb 25, 2016 Tailings ponds are massive earth structures used to store coarse and fine solids contained in the oil sands deposit and recover water back to the main processing plant. These ponds are temporary storage facilities and need to be reclaimed when no longer in use.Fine solids from tailings streams tend to trap large volumes of water, making pond reclamation challenging at best.

Due to the expense and effort of using settling tanks and ponds, some sites including the mine shown here now use belt presses to squeeze water out of the flocculated sediment. In addition to being faster, this system recycles more of the water and requires less water for washing and processing the sand.

Maximum allowable flow velocity through the settling pond is based on the average flow velocity at which point sediment re-suspension is likely to occur. Minimum desirable depth of settling pond is 0.6m. Pumped inflow must be appropriately baffled to dissipate inflow energy jetting and avoid the re-suspension of settled sediment.
