Introduction to this Special Issue on Tailings Storage
The construction activities involved removal and substitution of the old tailings (southern portion), emplacement of gravel columns over an area of about 10,000 m 2, and construction of the dyke's dam. Different technologies used during tailings storage to isolate the reactive materials can actually cause acid drainage problems.

Tales of Mercury-Containing Tailings | planetGOLD
In artisanal and small-scale gold mining (ASGM), after operations cease or move to new locations, tailings are often left behind without proper stabilization or containment measures. This poses a risk to the environment and human health, especially if tailings contain residual mercury (or other toxic materials).
Paste Backfilling on a Budget
In order to address these capital cost challenges a mobile paste plant (MPP) consisting of customized concrete equipment was developed that could process dry source material into paste backfill while being compact enough to move around. ... Tailings in slurry form from the mill – making up a portion of the recipe; the balance from dry …
A new look at the statistics of tailings dam failures
This article examines the statistics of tailings dam failures and challenges the conventional wisdom on their causes and consequences.
Tailings Ponds Up Close
Syncrude says tests have shown these lakes will evolve into natural ecosystems and after the final deposition of fine tailings, eventually support healthy plants, animals and fish. Composite tails combines fine tails with gypsum and sand, causing the tailings to settle faster than they would on their own, thereby speeding up the process of ...

Socio-Environmental Risks Linked with Mine Tailings …
Mine tailings material may contain ground rock, sand, clay, chemicals from the metallurgical process, and residual metals, minerals, and sulfides . In practice, there are different definitions for mine tailings from different points of view considering the experience of different professional disciplines involved in mine tailings management .
Socio-Environmental Risks Linked with Mine Tailings …
There is a need to define mine tailings in a clear, precise, multidisciplinary, transdisciplinary, and holistic manner, considering not only geotechnical and hydraulic concepts but also integrating environmental and geochemical aspects with implications for the sustainability of mining. This article corresponds to an independent study that …

Preface to the Thematic Section: Mine Tailings: Problem or
If these risks require the removal of the tailings to state-of-the-art tailing storage facilities or landfills, a re-mining approach could still be considered as an alternative. Resource recovery can then partially compensate for the remediation costs.
Mine Tailing
Mine tailings (MT) – MT are a mixture of small stone fragments and waste materials generated by mining operations to extract valuable minerals and metals from ore.
A Review on Remediation of Iron Ore Mine Tailings via …
Mining operations degrade natural ecosystems by generating a large quantity of mine tailings. Mine tailings remain in dams/open ponds without further treatment after valuable metals such as iron ore have been extracted. Therefore, rehabilitation of tailings to mitigate the negative environmental impacts is of the utmost necessity. This review …
