MINING TAILINGS AND MANAGEMENTS

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

TAILINGS MANAGEMENT

Tailings management is a mineral processing waste management issue. Tailings may be stored in a variety of ways, depending on their physical and chemical nature, the site topography, climatic conditions, and the socio-economic context in which the mine operations and processing plant are located. Tailings are most commonly stored in surface

Submarine Tailings Disposal

Producing just one gold ring generates 20 tons of mine waste. So where does all this waste go? Much of the waste generated from mining comes during the extraction process, after the target mineral is separated from the ore. This chemical laden sludge, known in the industry as tailings, are typically stored in earthen dams or impoundments.

How Is Mining Waste Recycled?

Recycling The Smaller Stuff. Tailings are the finely ground rock left over after mineral processing and they are mostly stored as a watery mix in tailing dams. Despite big improvements in the construction of tailings dams, they can fail, often with disastrous consequences. Some mines reduce this risk by 'thickening' the tailings.
