Tailings are a mixture of water, sand and clay found naturally in oil sands that remain following the mining extraction process. Tailings are transported by pipeline and deposited into ponds, where the majority of the solids – mostly sand – settle to the bottom. The remaining fluid (water and clay) is called Fluid Tailings (FT).
The idea of filtering water to obtain clean drinking water dates back to the Pharaonic Era, i.e. 4000 BC, where researchers found traces of a sand filter in Alexandria dating back to the year 50AD. This filter was used to filter water to obtain safe drinking water. Since then, the idea of using sand filters […]

Sand mining is the extraction of sand, mainly through an open pit (or sand pit) but sometimes mined from beaches and inland dunes or dredged from ocean and river beds. Sand is often used in manufacturing, for example as an abrasive or in concrete.It is also used on icy and snowy roads usually mixed with salt, to lower the melting point temperature, on the road surface.
The homogeneous sand filter has a 0.9–1 m deep bed of typically 0.85–1.7 mm sand (d 10 =0.9 mm) placed on a 50 mm layer of 4–8 mm or 75 mm of 6.7–13.2 mm gravel. Homogeneous sand of effective size up to 1.3 mm has also been used. The stated size ranges for sand and gravel are generally 5 and 95 percentiles.

In clays it is also not used because it is too slow. In silts and silt – clay mixtures the use of well points are aided by upper (0.60m – 0.90m long) compacted clay seals and sand-filtered boreholes (20cm – 60cm diameter). Upper clay seals help to maintain higher suction (vacuum) pressures and sand filters increase the amount of discharge.
Dry mining with a dozer trap; Heavy mineral sands (HMS) deposits comprising unconsolidated sand in an area where the water table can be managed, are often suited to dry mining with heavy earth moving equipment. Dry mining also allows greater flexibility around basement irregularities and is suitable for higher slimes deposits.

Medium sand 0.5-0.25 Fine sand 0.125-0.063 Silt 0.062-0.004 Cohesive sediment Clay 0.004-0.00024 Clay particles are plate-like in shape and have a maximum dimension of about 4 µm. Silt particles, like sand, have no characteristic shape; their size is between those of clay and sand with diameters ranging from 4 µm to 62 µm.
Depending on desired filter properties a woven metallic mesh screen, synthetic filter cloth, or a metallic plate can be used as the filter medium. The filter's floor, which holds the filtering medium, is reinforced by ribs between the floor and the filter plate so that it can support the weight and pressure from the cake.
