Mine tailings are the ore waste of mines, and are typically a mud-like material. Worldwide, the storage and handling of tailings is a major environmental issue. Many tailings are toxic and must be kept perpetualy isolated from the environment.
Environmental Risks From Mine Tailings ThoughtCo
10.08.2018· Tailings are a type of rock waste from the mining industry. When a mineral product is mined, the valuable portion is usually embedded in a rock matrix called ore. Once the ore has been stripped of its valuable minerals, sometimes through the addition of chemicals, it is piled up into tailings.
Mine tailings: How to effectively manage the risk
19.08.2020· While the tailings risk is unlikely to affect the actual mining effort; a collapsed tailings dam can destroy the mine’s value as well as a company’s reputation and licence to operate. Rather than look at tailings in isolation it actually makes more sense to include it as part of water management. The process is similar as the information requirements will differ in terms of what needs to
Mine tailings and their environmental legacy
14.10.2020· Mine tailings pose a number of risks including dam failure, leaching and wildlife exposure. These risks can impose serious consequences to aquatic environments and have detrimental effects on many wildlife species. In 2008, approximately 1600 ducks died after landing on bitumen polluted tailings in Alberta.
Mine Tailings an overview ScienceDirect Topics

What are tailings dams? IndustriALL
Tailings are the waste products from mining. Mechanical and chemical processes are used to grind up rock into a fine sand to extract the valuable mineral or metal from the rock ore. All the unrecoverable and uneconomic remnants from this process are waste. They include finely ground rock particles, chemicals, minerals and water.

Tailings.info Deposition Methods of Tailings
Restricting oxygen to the tailings by permanently placing them underwater will prevent oxidation and minimise the environmental problems associated with Acid Mine Drainage (AMD) (figure 3). With this in mind, the offshore disposal of tailings to natural water bodies is appealing but the actual overall environmental consequences of this technique are not fully understood. However, subaqueous

Tailings, ground up rock (uneconomical ore after processing) plus water, are contained in the TSF. The composition of the tailings will vary depending on the composition of the rock in the surrounding environment and the process of mineral extraction used at each mine. What is the water quality in a tailings management facility?
EarthTalk Can mine tailings help solve the climate
Yes, mining wastes ("tailings") could indeed be part of the solution to our climate woes. Researchers have shown that alkaline wastes--such as the slurries (semi-liquid mixtures), gravel and other industrial detritus that accumulate during and after mining projects--could be "reacted" with airborne carbon dioxide (CO2), which would not only sequester some of this most common of greenhouse gases but also

Tailings are the solid material plus varying degrees of runoff and process water (waste) remaining after the recoverable metals and minerals have been extracted from mined ore. The physical and chemical characteristics of the tailings vary with the nature of the ore, its geological setting and the climate where the tailings are placed.
From Tailings to Treasure? Miners Make Money
Mine sites typically manage tailings by constructing ponds secured by dams. According to the web site miningfacts.org, 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 construction or as backfill in underground mines. Now, some mining companies are figuring out ways to
