Taking the example of gold and copper extrac-tion at Ertsberg/Grasberg in West Papua, where up to 238,000 metric tons of toxic tailings were transpor-ted each day over the rivers of Agha-wagon and Otomona into the Ajkwa River and discharged into the Arafura Sea.

  • Environmental effects of copper mine tailings reclamation ...

    Anaerobically digested biosolids (treated sewage sludge) were applied to copper mine tailings (pH 8.0) in Princeton, B.C. to determine how well biosolids could achieve land reclamation on a site prone to wind erosion in a semi-arid climate (350 mm mean annual precipitation). In October 1992, biosolids at 62, 77 (two plots), and 179 dry tonnes/ha (dt/ha) were applied to 0.5 ha …

  • Model study of sloped tailings deposits

    Present tailings disposal methods are subject to limitations that warrent the development of alternative disposal techniques. A recently proposed method is the thickened discharge disposal method, which involves sloping tailings towards a downstream embankment, thereby reducing the height of the embankment required to store a given volume of waste material. The seismic …

    2021-8-9 · The two main factors leading to a decreased environmental impact per unit of electricity generated are scale and technology learning. The former factor, scale, relates to the pure size of the turbine, in particular its height and diameter. Height matters as more wind energy can be captured at higher wind shear factors and hub heights [51].

  • The reclamation of Sullivan mine iron tailings

    The Sullivan Mine iron tailings pose serious problems to reclamation which result from their high acid producing potential, extreme saline conditions, relatively high concentrations of heavy metals and tendency to cement upon oxidation. Oxidation results in the formation of a hard impermeable layer referred to as a ferruginous cap. Standard techniques of reclamation oriented towards …
