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.

Tailing Disposal Methods and Tailings Dam Construction Design

As there is seldom enough ground available on which the tailing of a flotation plant can be run to waste without being stacked, it is usual to impound it in some form of dam where the solids can be deposited and the water decanted off for return to the plant. It is generally advisable to recover as much of the water as possible in order not only to save the expense of obtaining a fresh supply ...

What are tailings dams? | IndustriALL

Rather than reinforced concrete, tailings dams use earth or rock to create a barrage. However, most tailings dams use the cheaper but more dangerous upstream method of construction, using the tailings themselves to create a barrier. The dam is then continually raised to accommodate more waste. These dams are more unstable and more prone to leakage.
