  • Gold mine tailings, the treasure place of recovery .

    As for the beneficiation process today, gold tailings contain a certain number of gold residues after the gold processing. It is wasteful to stack these tailings without reusing. According to incomplete statistics, emissions of state and local gold mine tailings are more than 20,000,000 tons each year, while the gold content is up to 1g/t, so the total content of gold is very considerable.

  • STATIC LIQUEFACTION IN TAILINGS DAM AND FLOW FAILURE

    Mine tailings can be classified as slurry, paste, or cake, according to its final solid/liquid ratio (S:L), which arises from the treatment given to the slurries at the end of the extraction process. Slurry undergoes no treatment, paste is a thickened slurry, and cake is a filtered slurry (see Fig. 1). In order to understand the phenomenon of tailings liquefaction it is necessary to answer the ...

  • Historic Gold Mine Tailings - Nova Scotia

    Tailings are a by-product of a gold mining process that was common in the late 1800s and early 1900s. Gold-bearing rocks that also contain arsenic were crushed and spread over liquid mercury to remove the gold. The mercury was then evaporated, leaving the gold. The remaining sand-like substance, known as tailings, was typically dumped into low-lying areas or lakes and streams near the mine ...
