A review of the risks posed by the failure of tailings dams

in a mine processing plant. Tailings often contain hazardous substances that can contaminate food chains, drinking water and the environment. Failure of tailings dams causes loss of lives, irreversible damages to ecosystems and large economic damages and therefore, there is a need for a cost effective service to both monitor operational and abandoned tailings dams, especially those in remote

Review: mine tailings in an African tropical

The lack of regulation for land-usage on or near to mine tailings has not helped this situation. Moreover, most countries in tropical Africa have not defined guideline values for heavy metals in soils for various land uses, and even where such limits exist, they are based on total soil concentrations. However, the risk of uptake of heavy metals by crops or any soil organisms is determined by

Tailings - Wikipedia

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 uses water

Brumadinho dam disaster - Wikipedia

The Brumadinho dam disaster occurred on 25 January 2019 when Dam I, a tailings dam at the Córrego do Feijão iron ore mine, 9 kilometres (5.6 mi) east of Brumadinho, Minas Gerais, Brazil, suffered a catastrophic failure. The dam is owned by Vale, the same company that was involved in the 2015 Mariana dam disaster. The dam released a mudflow that advanced through the mine's offices,

Reusing gold-mine tailings in cement mortars:

Substituting these mine tailings of Lefke-Xeros mine area in cement mortars would therefore take a leading role for the rehabilitation of the site. Reusing these mine tailings would remediate the contaminated land and seawater in the area and hence would help restoring the pre-mining environment and creating a land-use to benefit the local community.

Evaluation of soil intervention values in mine

The aim of this work is to show a methodological proposal for the analysis of soil intervention values in mine tailings in order to determine the intervention requirements in the commune of Andacollo in northern Chile. The purpose of this analysis is to guide the intervention policies of both private and public organizations. The evaluation method is based on the Dutch legislation.

mine tailings - Traduction en français - exemples anglais

Following their disposal into storage impoundments, mine tailings form a sloping delta along which hydraulic sorting of the particles occurs. Lorsque les stériles miniers sont évacués dans les zones d'entreposage, ils forment un delta en pente le long duquel une ségrégation des particules se produit. Some of these can also be used for mud dewatering, mine tailings, pond clean-up and

A Comprehensive Review on Reasons for Tailings

On a global scale, the demand for mineral products has increased substantially with economic development. Consequently, the mining of mineral resources results in the production and accumulation of a large number of tailings, causing many problems with respect to mining, the environment, and the economy. In the mining process, tailings must be reasonably treated to prevent them from entering
