  • Tailingsfo Dry Stacking of tailings

    Figures 1 and 2 show the La Coipa dry stack tailings facility in Chile. A typical moisture content of less than 20% is achieved by using a combination of belt, drum, horizontal and vertical stacked pressure plates and vacuum filtration systems (Martin, Davies et al. 2002). The term ‘dry cake’ or ‘dry stack’ is not entirely correct as the tailings have a moisture content several percent

  • Tailingsfo What Are Tailings? Their nature and production

    Tailings are generally stored on the surface either within retaining structures or in the form of piles (dry stacks) but can also be stored underground in mined out voids by a process commonly referred to as backfill. Backfilling can provide ground and wall support, improve ventilation, provide an alternative to surface tailings storage and prevent subsidence (EC 2004). Backfilling is

    Development of a dewatered tailings (dry stack) facility. The design basis for the TMF is to provide secure storage of approximately 974 million tonnes of tailings and 838 million tonnes of potentially acid generating and metal leaching waste rock and overburden. The expansion potential of each TMF option has also been examined, to accommodate a potential increase in total mined ore production

  • Tailings Wikipedia

    Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water

  • ICMM & Tailings management

    As the sandy residue of tailings gradually drains and becomes compact and dry, grass and other vegetation is planted to stabilise the environment. This is called the reclamation process. Before the water in the tailings can be used again, or discharged into the local drainage system, it must be treated to remove harmful substances that would pollute the environment or risk the health and

In addition to tailings storage, the dry stack provides encapsulation of mineralized waste rock to minimize the potential for oxidation processes to occur (Figure 3 shows the Dry Stack facility with relation to the RTP).
