Mine tailings: reprocess, recover & recycle
By removing tailings from a TSF, pumping them back to the concentrator and reprocessing them, this not only gives the possibility to recover residual metals, but also water. Water remains one of the greatest risks to mining operations globally. It is essential to the extraction of metals, and can be very expensive to source, treat and recycle ...

Tailings.info Deposition Methods of Tailings
Subaerial deposition exposes the beached tailings to oxygen and water allowing oxidation of infused sulphides and the production of acids (Newman, White et al. 2001), where the tailings have acid generation potential.
Mine tailing disposal sites: contamination problems
Mining practices and the absence of proper mine land reclamation has led to heavy metal contaminated sites with serious impact on the ecosystems and risk for human health. The origin of the contamination is often associated to mine tailing deposits because they are a source of the acid mine drainage (AMD). These areas are devoid of …
How do spiral concentrators work?
The spiral concentrator is a modern device that features high capacity at a low cost. It's designed to concentrate low-grade ore and industrial mineral slurries, using a combination of solid particle density and hydrodynamic dragging.
