Mining Waste an overview ScienceDirect Topics

Mining of 1 tonne of coal generates ∼0.4 tonne of mining waste and tailings, of which a majority is stored as aboveground (about 1300 ha) and belowground (∼1500 ha) spoil heaps. This is where reclaim treatments are carried out with the following aims: reclamation to forest, to forest and planting schemes, to planting schemes, rarely to parks and leisure, and occasionally to agricultureget price

The effluent from the tailings from the mining of sulfidic minerals has been described as "the largest environmental liability of the mining industry". These tailings contain large amounts of pyrite (FeS2) and Iron(II) sulfide (FeS), which are rejected from the sought-after ores of copper and nickel, as well as coal. Although harmless underground, these minerals are reactive toward air in the presence of microorganisms, which if not properly managed lead to acid mine drainage. get price

How Is Mining Waste Recycled? Ecocycle Australia

Rock and soil need to be moved to gain access to the coal, metal ores or other materials of interest. In some situations, it may be possible to sell rock and soil for a range of purposes as it is usually set aside for rehabilitation of the mine site after mining ceases. It’s used to contour the site and fill in some of the holes, and after re-vegetation the site may be restored to somethingget price

Waste Rock In Coal Mining

Waste Rock In Coal Mining; Tailings Wikipedia. Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.
