    Tailings Storage Facilities (TSFs)

    Tailings Storage Facilities (TSFs) Our metal and coal assets generate tailings (residues of mineral processing), which are stored in purposebuilt tailings storage facilities (TSFs). TSFs are specially designed reservoirs filled with tailings and water. We remove water through drains or evaporation while the tailings settle, gradually filling ...

     · Tailings can be managed through dewatering in a number of forms, broadly classified as conventional (unthickened) slurry (typically for gold tailings less than ∼45% solids), thickened slurry (∼45 to ∼55% solids), paste (∼70 to ∼75% solids), and filter cake (>∼75% solids). These forms are essentially four stages of progressive dewatering. The main differences between the forms are the:

    Tailings

    Trace quantities of metals such as copper, mercury, cadmium, zinc, etc. Additives used in processing, such as petroleum byproducts, sulfuric acid and cyanide. Tailings dams. Tailings, most often in the form of a wet slurry, are conventionally stored aboveground behind earthen dams. There is no comprehensive global registry of tailings dams.

    Jun 07, 2019 · Tailings are the materials left over following the processing of mined ore that separates the valuable metals or minerals from the host rock. Tailings are not the same as waste rock, the latter being soil or rock or other material that covers or surrounds an orebody and that is displaced during mining but is not processed.
