Introduction. 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. This process of product extraction is never efficient, nor is it possible to ...

The study area has 540 m in the east–west direction and 440 m in the north–south direction, and the maximum depth is 10 m. The geometry of the dam and the sampling design are shown in Fig. 2, where it is seen that the sampling mesh is almost regular in the eastern part of the tailings.Because of this particularly sampling grid …

Dewatering tailings to higher grades than paste produces a stable deposit that typically does not require retention dams and is called a "dry stack." A proposal of different dewatering techniques applied in the fine tailings produced after final desliming phase, obtained from the treating of phosphatic ores, is the main objective of this work. …
What are tailings? Tailings is a common by-product of the process of extracting valuable minerals and metals from mined ore. They usually take the form of a liquid slurry made of fine mineral particles, created as mined ore is crushed, ground and processed. Effective tailings management is integral to the safe and sustainable production of ...
This conceptual paper argues that full cost accounting could fill a gap in the new Global Industry Tailings Management Standard by bringing knowledge of externalities to account. Tailings dam management continues to fail the industry, environment and society as one catastrophic disaster follows another. Parties involved …
The flotation by surface sulphidisation of the oxidized copper-cobalt-bearing ore from Kimpe (1.97% Cu; 0.66% Co) was studied in order to evaluate its behavior by the analysis of its most ...

The Global Industry Standard on Tailings Management is directed at Operators and applies to tailings facilities, both existing and to-be-built. It makes clear that extreme consequences to people and the environment from catastrophic tailings facility failures are unacceptable. Operators must have zero tolerance for human fatalities and strive ...

The disastrous impact of a tailings dam failure is more far-reaching than that of a water retention dam failure. This paper analyzes the movement characteristics of mudflow during a tailings dam failure using physical models based on the Wadugou tailings impoundment. The physical models were built according to the similarity laws …

Tailings storage is a prescient issue in mining, representing a visible and destructive liability. Dewatering tailings to a paste-like consistency is a popular option to reduce tailings volumes and increase dam safety, but dewatering further to a bulk cake consistency has mostly been reserved for small operations in locations where seismicity …
