Management of mine tailings is a major environmental issue and economic burden. • Submarine tailing disposal and deep-sea tailing placement practices are increasing.
Thickened tailings, as the name suggests, involves the mechanical process of dewatering low solids concentrated slurry (Fourie 2003). ... do not require deep cone or paste thickening technology, bleed water upon deposition and can be transported using conventional centrifugal pumping.
Paste tailings are defined as tailings that have been significantly dewatered to a point where they do not have a critical flow velocity when pumped, do not segregate as they deposit and produce minimal (if any) bleed water when discharged from a pipe (figure 1).

Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue or slickens, terra-cone (terrikon), are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.
Tailings from uranium-ore processing have been used extensively in some areas of the West to construct buildings, etc. This subsequently has been determined to be highly undesirable, however, due to radiation from radioactive components contained in these tailings.
A tailings dam is typically an earth-fill embankment dam used to store byproducts of mining operations after separating the ore from the gangue. Conventional water retention dams can serve this purpose, but due to cost, a tailings dam is more viable.
TAILINGS "Consider a picture such as Nickel Tailings #34 from Burtynsky's "Mines and Tailings," a series devoted to the environmental aftermath of metal mining and smelting.Under a cool, grey sky, against a wintry violet backdrop of distant trees, a brilliant orange river swerves toward the camera from within a deep brown landscape.
The Marampa Iron Ore Project consists of developing a tailings reprocessing operation at the Marampa mine in Sierra Leone, transporting finished product by road (40 km) to a nearby port and barging the product (60 km) out to deep water for transhipment onto handymax, panamax or capesize ships.
