Mine Waste Transfer and Disposal Methods

In response, mining engineers have developed clever ways of waste management, making the mining industry one of the few that actively recycle their own waste. Overburden is used for reprocessing, contouring land, and as a construction aggregate for buildings and roads. Mine tailings are reused for producing clay, tiles, glass, and concrete.
