  • The dangers of tailing dams on the planet Clean Mining

    Nov 25, 2019· Depending on who you talk to, tailing dams are considered an engineering marvel and mining necessity, while others declare them as an unnecessary hazard and major environment threat. Statistics are equally divergent. In the decade between 2007 and 2018, some 27 serious tailing dam failures were reported.

  • What are tailings dams IndustriALL

    Tailings dams need regular maintenance and monitoring to ensure that there is sufficient drainage and the dam is strong enough to contain the mining waste. Tailings dams can pose a threat to local wildlife as birds and animals bathe in and drink from the contaminated waters.

    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 finding alternate uses.

    Sep 21, 2020· In a tailings discharge of a Gold mine we have 30 to 40% solids and 60 to 70 % solids. In the solids it is still ore so it will contain Iron, copper, silver and gold not recovered in the process. The solids also pose a great treat to fishing reefs as they will accumulate cover and destroy the reefs where marine life is abundant.

    When gold-bearing rock is processed and the gold is extracted, the remaining material is moved to tailings dams as waste, as was the case at the Merriespruit No. 4 facility. As is typical with gold tailings in South Africa, the Merriespruit tailing dam was constructed using the "upstream semi-dry paddock" method, where a "daywall" perimeter is constructed and allowed to settle and dry out (typically carried out during the day and supervised) before slurry is placed in the "nightpan

  • Tailing Disposal Methods and Tailings Dam Construction Design

    As there is seldom enough ground availe on which the tailing of a flotation plant can be run to waste without being stacked, it is usual to impound it in some form of dam where the solids can be deposited and the water decanted off for return to the plant. It is generally advisable to recover as much of the water as possible in order not only to save the expense of obtaining a fresh supply
