摘要： Systems and methods for dewatering mine tailings. The systems and methods include distributing a slurry of high permeability material on a sloped surface to define a high permeability layer and subsequently distributing a slurry of low permeability mine tailings on the high permeability layer to define a low permeability layer that is vertically above and in contact with the high permeability layer. The sloped surface defines a non-zero surface grade, and natural slopes of both the slurry of high permeability material and the slurry of low permeability mine tailings are within a threshold grade difference of the surface grade. In some embodiments, the systems and methods may include augmenting the slurry of high permeability material and/or augmenting the slurry of low permeability mine tailings to adjust the natural slope thereof.
