Environmental Containment Solutions for Tailings ...

Tailings are the waste product that results from mining, crushing, grinding and chemically treating ore. The tailings storage facilities (TSF), also known as processed ore containment facilities, consist of crushed rock, water, and chemicals. In the long term, the tailing facilities become part of the topographic form. An important function of these tailings facilities is to prevent the ...

MINE TAILINGS CONTAINMENT RECLAMATION CONSTRUCTION The reclamation of Moon Creek had six primary construction elements: 1. Removal of an estimated 88,000 cubic yards flotation tailings, contaminated soils, and waste rock 2. Construction of an onsite combined waste containment to safely contain these materials 3. Closure of the mine workings (shafts and adits) 4. Rehabilitation of about

Tailings dam - Wikipedia

The standard of public reporting on tailings dam incidents is poor. A large number remain completely unreported, or lack basic facts when reported. There is no comprehensive database for historic failures. According to mining engineer David M Chambers of the Center for Science in Public Participation, 10,000 years is "a conservative estimate" of how long most tailings dams will need to maintain structural integrity. The lack of any comprehensive tailings dam database has prevented meaningful analysis, either gross

Mine tailing disposal sites: contamination problems ...

18/11/2017  An additional important problem associated with mine tailings is the pH and composition of the mine drainage that is defined by the reaction of minerals in tailing deposits with external agents such as atmospheric oxygen. An important example of those reactions occurs when pyrites and other sulfide minerals. Sulfide minerals may occur naturally in mines, and very often, metallic sulfides are ...

Tailings are also called mine dumps, culm dumps, slimes, tails, refuse, leach residue, slickens, or terra-cone ... Phytostabilisation is a form of phytoremediation that uses hyperaccumulator plants for long-term stabilisation and containment of tailings, by sequestering pollutants in soil near the roots. The plant's presence can reduce wind erosion, or the plant's roots can prevent water ...

18/11/2019  Proper containment of tailings reduces the risk to people and the environment, and when decommissioning a mine, thickened tailings facilities are easier to rehabilitate. To a growing extent, thickened tailings are also used for underground mine backfill. This can increase productivity and reduce mine cycle times as well as surface TSF disposal ...

18/11/2017  Mining practices and the absence of proper mine land reclamation has led to heavy metal contaminated sites with serious impact on the ecosystems and risk for human health. The origin of the contamination is often associated to mine tailing deposits because they are a source of the acid mine drainage (AMD). These areas are devoid of vegetation due to the harsh soil conditions that prevent

Mine tailings are any byproducts leftover from mining or extraction of resources. These include rock particles, chemicals, and water. These materials often experience chemical reactions which create more byproducts including acid and dissolved metals. These additional byproducts leach into our waterways and water supplies. Tailings are often toxic.

MANAGEMENT OF TAILINGS: PAST, PRESENT AND FUTURE

The forms of tailings containment and method of construction and facility raising varies from region to region. Upstream construction, using tailings where possible, is widely employed in southern Africa, Australia and the south-west of the USA, which have in common a dry climate. Centerline and downstream construction, by contrast, is usually employed in wet and/or high seismic regions. While ...

Tailingsfo Surface Tailings Containment

Co-disposal is a mixing of tailings and coarse mine waste to produce a single waste stream (Martin, Davies et al. 2002) or by co-placement seperating the two waste streams in a single storage facility. This method of tailings storage is most suitable to the backfilling of voids (underground and open pit), the covering of conventional tailings storage methods and the construction of elevated ...

Mine Tailings - groundtruthtrekking

Tailings containment facilities are regarded as the world's largest man-made objects. Terminology. Mine tailings' size and composition depends on the mining method. For hardrock metal mines, tailings are usually a very fine mud or powder, which is left over after ore is crushed and valuable minerals are extracted from it. Tailings may also contain chemicals used for mineral extraction ...

Waste Containment Systems for the Mining Industry

Liners for Tailing Containment When gold, silver, copper, and uranium go through the heap leaching process, they leave behind byproducts known as tailings. These sand-like leftovers can be dangerous if accidentally dispersed. Uranium tailings, for instance, contain 85% of uranium’s total radioactivity—which can prove hazardous or fatal if introduced to waterways or food supplies. For this ...

MINING TAILINGS AND MANAGEMENTS

Tailings consist of ground rock and process effluents that are generated in a mine processing plant. Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings. The process of beneficiation of run of the mine ores and subsequent disposal to surface containment facilities exposes elements to accelerated ...

Setting a standard for tailings dam management

• The storage must be designed with mine closure in mind, so as to create a permanent, maintenance free deposit that does not pose any unacceptable environmental impact or risk. To highlight these differences, the term tailings storage facility (TSF) is often used, instead of dam. In some cases, tailings storage can be successfully achieved with minimal requirement for embankment dams in the ...
