  • Tailings Wikipedia

    Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue, slickens, or terra-cone (terrikon), 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

  • Tailings.info Backfill of Tailings to Underground Workings

    Tailings can be stored below ground in previous worked out voids. The tailings are generally mixed with a binder, usually cement, and then pumped underground to fill voids and help support an underground mine. For example a ‘room and pillar’ mining operation that uses backfill will be able to extract the insitu pillars containing ore.

  • Hydraulic mining Wikipedia

    Hydraulic mining, or hydraulicking, is a form of mining that uses high-pressure jets of water to dislodge rock material or move sediment. In the placer mining of gold or tin, the resulting water-sediment slurry is directed through sluice boxes to remove the gold. It is also used in mining kaolin and coal.. Hydraulic mining originated out of ancient Roman techniques that used water to excavate

  • Tailings.info What are tailings? Their nature and production

    INTRODUCTIONNATURE OF TAILINGSPRODUCTION OF TAILINGSTAILINGS CHARACTERISTICSTailings consist of ground rock and process effluents that are generated in a mine processing plant. Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings. This process of product extraction is never 100% efficient, nor is it possible to reclaim all reusable and expended processing reagents and chemicals. The unrecoverable and uneconomic metals, minerals, chemicals, organics and process water are dis.

  • Practical Considerations in the Hydro Re-Mining of Gold

    Hydraulic re-mining is generally best suited to reclamation of hydraulically deposited tailings and fine sands. Coarser residues are better re-mined by mechanical means. Mechanical reclamation is an expensive option for finer tailings, and dredging is generally more expensive than hydraulic re-mining, especially where labor rates are low.
