Tailings storage facilities (TSFs) are known as a time-bomb. The numerous failures of TSFs and the heavy catastrophic consequences associated with each failure of TSFs indicate that preventing measures are necessary for existing TSFs. One of the preventing measures is to construct catch dams along the downstream near TSFs.

A large number of tailings ponds formed by slag accumulation have become serious environmental hazards. Spatially high potential energy and long-term accumulation may result in gradient-changing seepage pollution. The assemblages of phytoplankton and bacteria are widely used as assessment indicators.
A tailings storage facility is a facility used to contain tailings. This can include a tailings dam (impoundment and pond), decant structures and spillways. A tailings storage facility can also be open pits, dry stacking, lakes or underground storages. A tailings dam is a tailings embankment or a tailings disposal dam. The term "tailings dam
The conventional approach to tailings storage is to thicken the tailings just to the extent that they can be pumped using robust centrifugal pumps by pipeline to a surface tailings facility, where the tailings are deposited sub-aerially (that is, above water and on the
The storage of large volumes of tailings has become an issue for Canada׳s oil sands industry. and stimulation of microbial consortia, since oily films and bitumen were observed on the surface of pond (Suncor Energy Inc., 2012, Syncrude Tailings ponds are heterogeneous sources which differ in pond chemistry and microbial
Numerical modelling According to the geotechnical investigations performed on site for the 2 leaching ponds, the lithology in the area is the one presented Table 1. Tailings have thicknesses comprised between 4.2 m and 22.8 m. This can be characterized as sand, clayey sand, sandy clay or silty sand.
The tailings pond is used to store metallic and non-metallic mine tailings and other industrial waste and the Li WQ, Chang L (2018) A combination model with variable weight optimization for short-term electrical load forecasting.

At tailings ponds taken out of service, dust emission protection can be ensured by flooding of beach. Constant water level above the beach surface is maintained as a gathering pond but this needs appreciable energy and water resources. Lebedinsky GOK suppresses dusting at tailings storage facilities by spraying.
Minerals contained in local tailings can be used in our HD Fluid ; Energy can be created from slurries and repurposed to regenerate electricity; Pumped storage provides the lowest levelized cost of energy storage for durations of > 4 hours and is a mature technology of 100+ years, it makes up 98% of global deployment
PURPOSE. This document provides guidance for managing risks associated with working on and around bodies of process affected water ponds such as tailings ponds. The intended audience includes oil sands companies and employers that work in tailings operations but is not limited to health and safety, risk management, maintenance,
The Global Tailings Review convened by the United Nations Environment Programme (UNEP), the Principles for Responsible Investment (PRI) and the International Council on Mining and Metals (ICMM) launched the Global Industry Standard on Tailings Management. The Standard was developed by a multi-disciplinary Expert
All of the aforementioned have produced a movement in society that demands safe and responsible management of mine tailings by mining companies, demanding (i) greater economic investments in the
The storage capacities of phase I and phase II tailings ponds were measured at 204,798.63 m3 and 148,291.27 m3, respectively, with a storage capacity change of 56,031.51 m3. Moreover, the minimum flood control dam widths, minimum free heights, and dam slope ratios of the tailings pond were determined to comply with the flood control
A catastrophic tailings dam failure disaster occurred in Brumadinho, Brazil on 25 January 2019, which resulted in over 270 casualties, 24,000 residents evacuated, and a huge economic loss. Environmental concerns were raised for the potential pollution of water due to tailings waste entering the Paraopeba River. In this paper, a detailed analysis has
Main functions of tailings pond: safe and rational storage of tailings, environmental protection, conservation of energy and water. A tailings pond usually
The findings reveal that (i) Cd, Pb, and Hg are the prominent pollutants across the non-failed TSF sites in China; (ii) lead‑zinc and tungsten mine tailings
Tailings are the left-over materials from the processing of mined ore. They consist of ground rock, unrecoverable and uneconomic metals, chemicals, organic matter and effluent from the process used to extract the desired products from the ore. Tailings are stored in tailings storage facilities (TSFs). TSFs are dynamic structures that are
Nov 3, 2011. MONTROSE COUNTY – In its next step toward the construction of the Piñon Ridge Uranium Mill in the west end of Montrose County, Energy Fuels Inc. announced last week it received approval from the Environmental Protection Agency on the mill''s tailings impoundment and evaporation pond facilities. These two facilities will process
The utilization of mineral resources plays an important role in supporting and promoting economic development and social progress. As a necessary facility for the development and utilization of mineral
The mechanisms and causes of the sudden failure of the Aznalcóllar tailings pond is presented by Joaquín Martí et al. (Spain). The dam underwent displacements of up to 55 m along a 700 m length, releasing large quantities of acidic waters and 5.5 million m 3
Four conditions must all be present for a tailing dams flow failure to occur: (1) tailings must experience contractive behavior; (2) tailings must be fully saturated;
Chile''s first floating solar farm has been installed on a tailings pond located at Los Bronces mines. The 84-kWp pilot should generate 153 MWh per year. News & Technology for the Global Energy

In the past thirty years many mining projects in Chile and Peru have used: (i) polymeric geomembranes and (ii) design-and-build cutoff trenches, plastic concrete slurry walls, and grout curtain systems to control seepage at tailings storage facilities (TSFs). Geosynthetics are a viable alternative at a TSF dam for clay cores or impermeable
