Mining Waste an overview ScienceDirect Topics

For example, in India, in the Sukinda mining area, around 7.6 metric tons of solid wastes have been generated in the form of rejected minerals, overburden material and waste rock, and subgrade ore that have caused environmental degradation, mainly creating lowering of the water table as well as deterioration of surface and groundwater quality

Waste RockTailingsMine WaterChemicals Used in ProcessingWaste rock is the rock that is excavated to reach the ore. The amount of waste rock that needs to be removed depends on the geometry and location of the ore body, along with the mining method used and the composition and stability of the rocks. The ratio between waste rock and ore production is called the stripping ratio. For example, a stripping ratio of 2:1 means that 2 tonnes of waste rock needs to be 在sgu.se上查看更多信息

Mining Waste Treatment Technology Selection

Solid mining waste may present a risk from direct contact with human or ecological receptors. In historic mining areas, there is often little separation between the mining areas and residential areas; thus, people living in these areas are exposed to mining waste on a regular basis.

Rock or Solid Mine Waste. Open pit mining has several stages of waste. First, to access the actual seams or veins of ore, the top layers of rock, or overburden, must be removed. Once the overburden has been removed, the seams can be extracted. When extracting the seams, the additional waste rock will be removed to get to the actual ore, called

Mine Waste an overview ScienceDirect Topics

Solid mine waste (overburden, waste rock, solidified tailings, slag, dust) can be used as backfill in underground or open pit workings; stored in piles on site or underwater to prevent occurring acid mine drainage and utilized in construction of roads and dams at the mine, or recycled. Wastewater can be recycled and reused for dust suppression
