• High density slurry and paste tailings, transport systems

    high density tailings and a paste slurry From a pipeline flow perspective, it is necessary to understand the changes in flow behaviour as solids concentration increases and it is not always necessary to define the slurry as thickened or a paste tailings The same applies to the preparation and disposal requirements It is nonetheless, important to

    the process of thickening the tailings to a heavy slurry prior to disposal, thus creating a selfsupporting deposit of tailings Because the settling pond is eliminated, failure within the well consolidated tailings material would only result in local slump, without flow It is also noted that the system can inhibit acid drainage The fines in

  • Tailings Solutions for the Future | Weir Group

    Dewatering involves removing liquid from waste slurry so that the remaining solids can be deposited in a tailings storage facility or returned to the site from which it was mined as backfill There are several dewatering methods to render waste slurry to differing degrees of dryness, ready for transport from the plant to the deposition site
