Alternative Uses of Tailings | Tailings

With substantial reductions in both the volume of tailings left to store and rehabilitation costs, an estimated 60 to 80 per cent of the tailings' processed water can be recovered prior to backfilling, while the structural stability once filled offers a safer workspace for employees to continue. In this way, utilising the mine's own tailings for backfill is not only a resource to the mine

Tailings.info What Are Tailings? - Their nature

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 reclaim all reusable and expended processing reagents and

Environmental Risks From Mine Tailings -

10.08.2018· When rain falls on tailings, it leaches away materials that can create water pollution, for example, lead, arsenic, and mercury. Sulfuric acid is sometimes produced when water interacts with tailings, or it can be a by-product of ore processing. As a result, highly acidic water leaks from the tailings and disrupts aquatic life downstream
