Mine Waste Transfer and Disposal Methods
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, there is additional waste rock that must be separated from the ore.
