Mine tailings are the waste solid residuum after separation of valuable minerals from economically worthless minerals (gangue). After extraction and beneficiation, the residuals from mineral recovery are normally discharged as a hydraulic fill (aka slurry) composed of finely ground gangue (sub-micrometer to sand-sized particles), chemicals, and ...

The 2024 Tailings and Mine Waste Conference will be held November 10-13, 2024 in Westminster, Colorado, USA. Mine Waste managers, engineers involved with tailings management and reclamation ...
Several types of waste are generated in a mine, but three types stand out with the largest volume: waste rock, tailings and mine water. In some cases, the mine uses certain chemicals such as cyanide in the processing stage. These chemicals often account for a small volume of the total waste but can pose a large risk due to their high toxicity.
In August 2014, a tailings dam breach at the Mount Polley Mine in British Columbia released 5 million cubic meters of toxic waste into nearby creeks and a lake. The failure was so violent that it ripped mature trees from the …
Geotechnical, environmental and regulatory issues related to tailings and mine waste management will be highlighted at this hybrid conference, hosted by Colorado State University (Civil & Environmental Engineering Department). We are proud sponsors of this event and will present a short course.
AMD, another major problem in tailings management, occurs in tunnels, surface and/or underground mines, waste rocks, and tailings at active and passive (abandoned) sulfide-rich mines. AMD is a multifaceted process as it covers chemical/biological reactions changing with ecological situations.

The biggest waste streams both in metal value and in volume in mining are tailings, which create long-term environmental liabilities to the companies (Wang et al., 2014) due to the potential for acid rock drainage generation (Simate and Ndlovu, 2014) from sulphidic tailings.Instead of considering the tailings only as an environmental challenge, the tailings …
Tailings dams are built gradually over time, as the mine produces more waste and hydro dams are constructed all at once. This means that safety oversight can change significantly if the mine changes operators, if the type of ore changes as the mine reaches deeper deposits, or if the mining company comes under economic pressure.
Stability of tailings dams will be discussed in a webinar on January 20 th, 2022.. The International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE) Technical Committee TC221 on Tailings and Mine Wastes is organizing a Tailings and Mine Waste Webinar taking place on 20th January 2022. This webinar was motivated by answers given to a brief …
Each year, mining operations generate large volumes of mine waste, including tailings. According to the International Institute for Environment and Development's (IIED) Mining, Minerals, and Sustainable Development Project (MMSD), there are approximately 3,500 active mining waste facilities worldwide, consisting of waste rock dumps and tailings impoundments.

Mine tailings are a major waste stream generated in mining operations. Tailings are the waste material left over after the valuable component has been removed through processing.
Proper management of tailings and mine waste is essential in the mining industry. Tailings are the by-products left after extracting valuable minerals and metals from ore. These …

What is mine waste? Mine waste is the material left over after mining. It consists of tailings - the material that remains after mined ore is milled and concentrated, waste generated during ore processing such as slag, leaching solutions and residues, and waste rock, and material that was removed to get to the ore.
