Reclamation of the oil sand mining industry's first tailings pond, Suncor's Pond One (Wapisiw Lookout), was completed in 2010. Strict regulations and a comprehensive monitoring program are in place to ensure that reclamation and end land use outcomes are met. All oil sands mining operators plan mine development to enable reclamation of the site once mining operations are completed. In ...

 · Mining operations often generate tailing dams that contain toxic residues and are a source of contamination when left unconfined. The establishment of a plant community over the tailings has been proposed as a containment strategy known as phytostabilization. Previously, we described naturally occurring mine tailing colonizing plants such as Acacia farnesiana, Brickellia coulteri, Baccharis ...

This concern includes establishment of plant communities with biotransport capabilities with root depths well into the tailings, as well as planteating, burrowing, and lodgebuilding animals, and the microbiological and invertebrate biota in soils. The effects of these processes on the TMAs is largely dismissed with a cursory discussion such as the Denison EIS, at p. 539, which concludes ...

Past mining activities have left a legacy of abandoned mine tailing deposits whose metal contaminants poses serious risks to ecosystems and human health. While the development of a vegetated cover in mine tailings can help in mitigating these risks, the local factors limiting plant establishment in these sites are not well understood, restricting phytostabilization efforts.

Gold Cyanidation

Gold Cyanidation

Many old mines, and some current mines, simply place cyanide waste into the mine tailings ponds along with other mining waste. Failure of a tailings dam containing cyanide can be a massive environmental problem, resulting in the sterilization of large areas downstream. In 2000, a tailings dam failure in Romania dumped an estimated 100 tons of cyanide into a river system, contaminating drinking ...

Tailings

In mining, tailings 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 extraction of minerals from ore can be done two ways: placer mining, which ...
