  • Mining Waste Environment European Commission

    Waste from extractive operations ie waste from extraction and processing of mineral resources is one of the largest waste streams in the eu it involves materials that must be removed to gain access to the mineral resource such as topsoil overburden and waste rock as well as tailings remaining after minerals have been largely extracted from the ore.

  • Mining Waste Products

    Although the released finegrained tailings were the waste produced during mining and mineral processing they are still very enriched in metals in comparison with natural sediments so much so that it has been common practice for old tailings dumps to be successfully remined when either the value of the mineral has increased or the technical ability to concentrate the mineral has improved.
