  • Towards safer, more sustainable handling of mine tailings

    Jun 10, 2019Mining involves the processing of mined ore to separate valuable minerals, leaving behind huge volumes of waste tailings. Driven by mining volumes, globally generated tailings are estimated to total ~3.2 bn tons for copper and ~1.8 bn tons for iron per annum.

  • Waste rock and tailings – Waihi Gold

    Tailings are a slurry of around 30% solids and are deposited from the crest of the waste rock embankment via a series of spigots. Fresh tailings are deposited above water onto previously placed tailings. The material is predominantly silt size, but also contains clay and sand sized particles.

  • Tailings

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

  • Remediating mine tailings and recovering gold

    May 25, 2013The first commercial bioleach facility in North America with the purpose of remediating toxic mine tailings will start construction this year in Manitoba. The facility, being built by BacTech Environmental Corporation, is a $22-million plant that will process 100 tonnes of tailings per day on a 24-hour schedule for about seven years.

  • Mining and Water Pollution — Safe Drinking Water Foundation

    Dec 17, 2016Mining affects fresh water through heavy use of water in processing ore, and through water pollution from discharged mine effluent and seepage from tailings and waste rock impoundments. Increasingly, human activities such as mining threaten the water sources on which we all depend.

    The tailings are contained within the impoundment facility and once it reaches capacity, the impoundment is reclaimed with a designed cover system used to minimize erosion and infiltration, while maintaining containment of the materials, protecting the environment and achieving post-mining designated land use.

  • The future of tailings

    In recent times, tailings processing has become a critical aspect of mining operations globally, with an increased focus on water recovery, safety and sustainability. Combined with the stringent accountability that mine operators have to local communities, tailings management is now a significant consideration, with processing requirements and technology changing rapidly.

  • What are tailings dams?

    Tailings dams are used to store water and waste that come as by products from the mining process. It is estimated there are at least 3,500 tailings dams around the world. But as there are around 30,000 industrial mines, the number of tailings dams is likely to be much higher. Tailings dams can be

  • From Tailings to Treasure? A New Mother

    Tailings may be dumped in or near water or transported by wind or water to contaminate the surrounding area. Mine sites typically manage tailings by constructing ponds secured by dams. According to the web site miningfacts, another strategy is to produce thickened tailings, which are pressed or have chemicals added to remove excess water. Thickened tailings can be mixed with cement and used in
