tailings recycling processing

  • Mining tailings and wastewater management

    Water contaminated by the Mining industry is also referred to as Tailings. Tailings contain waste from the extraction processes such as equipment wash water, and from the refining process, often discharged in the form of slurry, which is a mix of fine gangue particles, chemicals and water, to large retention facilities called Tailing Dam or Tailing Ponds.

    May 10, 2019Being able to process tailings into usable materials would be good as they are already a bit too much of an issue for the product gained in smelting. Perhaps being able to produced 'encased trailings' by processing them with stone or crushed rock would enable them to be suitably diluted in rock form, that could be placed with minimal pollution.

  • How can metal mining impact the environment?

    As the amount of waste rock in open pit mines is commonly two to three times the amount of ore produced, tremendous volumes of waste rock are removed from the pits and deposited in areas nearby. Waste piles from processing, such as tailings impoundments, leach piles, and slag piles vary in size, but can be very large.

  • How Is Mining Waste Recycled?

    Recycling The Smaller Stuff. Tailings are the finely ground rock left over after mineral processing and they are mostly stored as a watery mix in tailing dams. Despite big improvements in the construction of tailings dams, they can fail, often with disastrous consequences. Some mines reduce this risk by 'thickening' the tailings.
