    Hydraulic gold mining in the Sierra Nevada produced large volumes of sediment from 1853 to 1884. Sediment production decreased substantially after 1884 when hydraulic mining was enjoined. More than a billion cubic metres of mine tailings were produced in the Sierra Nevada, particularly in the Yuba, Bear, and American basins (Figure 1).

    Hydraulic mining originated out of ancient Roman techniques that used water to excavate soft underground deposits. Its modern form using pressurised water produced by a monitor came about in the 1850s during the California Gold Rush. FDPs monitors project a concentrated jet (for maximum energy impact) to erode the tailings in sections.

  • Dewatering amp; processing tailings with centrifuges

    In mining, the term tailings refers to finegrained residues in the form of sludges. They are created during the processing of ores and minerals. The resulting waste water or overburden sludge is partly contaminated with chemicals. Tailings are a risk to the environment when stored in sludge ponds.

    11ensp;0183;ensp;Hydraulic remining is generally best suited to reclamation of hydraulically deposited tailings and fine sands. Coarser residues are better remined by mechanical means. Mechanical reclamation is an expensive option for finer tailings, and dredging is generally more expensive than hydraulic remining, especially where labor rates are low.
