    Historically, tailings were disposed of in the most convenient manner, such as in downstream running water or down drains. Because of concerns about these sediments in the water and other issues, tailings ponds came into use. The sustainability challenge in the management of tailings and waste rock is to dispose of material, such that it is inert or, if not, stable and contained, to minimise water and energy inputs and the surface footprint of wastes and to move toward findin

  • gold mine slime dump recycling - lowenrestaurant.ch

    Gold-mining residues typically fall into one of three categories comprising slime (particle size of about 75% passing 74 μm), sand (about 10–20% passing 74 μm) and waste rock. Since the slime and sand has been previously processed, it typically has a low gold grade ( 1.0 g/t) and will provide relatively low recovery efficiencies, in the ...

  • Surface recovery - DRDGOLD

    The retreatment business is high-volume and low-risk. Vast quantities of material are processed monthly through the plant in order to recover gold from old mine dumps at a recovery rate that varies depending on the material being treated. As each old dump or dam is depleted, others are brought on stream.
