Tailings.info Thickened Tailings Storage A discussionThickened tailings, as the name suggests, involves the mechanical process of dewatering low solids concentrated slurry (Fourie 2003).

The case of tailings thickening

innovative solutions for tailings managementtailings thickeners generate highdensity underflows with high yield stress, which are often pumped long distances to a final tailings impoundment area. the tailings are then deposited, dried and eventually rehabilitated. the etd process is able to rigidify tailings at the point of disposal by initiating instantaneous water release from thealrosa adds tailings thickening complex at udachny n12oct 02, 2020· the tailings thickening complex comprises of a pump system, a cyclone cluster, and two 28 m in diameter thickeners. the complex uses centrifugal force to extract most of the recycled water from the tailings. the water is further reused, and the remaining sand after thickening goes to the tailingsa comparison of alternative tailings disposal methods thickened tailings disposal involves producing a tailings slurry that tends not to segregate upon placement, using highdensity or deepcone thickeners. slurry densities of thickened tailings generally range from 50 to 70% solids by weight. the thickened slurry can be pumped using centrifugal pumps.tailings mineral industry solution westechinctailings paste thickeningtailings paste thickening. the advantages of paste thickeners in tailings circuits have been wellpaste thickening considerations for backfill vs. tailingsthe difference between a 10in. slump and nonthickened tailings can be 7% to 10% solids by weight. to pinpoint a percent solids in a process like this vs. athickened tailings a water and energy consumptionthickened tailings a water and energy consumption perspective j.h.l. möller et al. 216 paste 2012, sun city, south africa table 2 input parameters parameter value concentrate tailings thickener dry tonnage (maximum) 212.6 t/h thickener feed solids concentration 11.2%m thickener feed slurry flow rate 1,748.5 m3/hthickenedandpastetailingspipelinesystems design procedurefigure 1 nonnewtonian thickened tailings (τ. y = 70 pa, k. b = 0.060 pa.s) table i presents measured pump performance derating parameters for three typical thickened tailings slurries with varying percentages of coarse particles. the test work has been conducted using a Xinhai 6/4 pump with a 365 mm diameter impeller.
