  • Waste Disposal Massachusetts Institute of Technology

    Improper waste disposal is often the largest of mine and refinery pollution Waste is generally categorized into two different types: tailings and waste rock stockpiles. Tailings have the most damage potential because they tend to be composed of smaller, finely milled particles, whereas waste rock stockpiles are made up of coarser particles, which are not absorbed into the water and the ground

  • Mining DARES TECHNOLOGY Looking Forward

    Mining wastes are deposited on the surface to form vast dumping grounds (waste dumps). Landslides, erosion and subsidence of waste dumps are a challenge for the mining industry because they represent a potential source for environmental problems which have significant negative impacts on their surroundings. Therefore, waste dump monitoring and early warnings of environmental hazards are

  • Disposal Methods on Solid Wastes from Mines in

    With the development of backfilling technology, more and more solid waste from industry, such as tailings, waste rock and smelter could be used as backfill materials. For a mine transiting from open-pit to underground, it is very important that more attentions be paid to backfilling technology for the purpose of solid waste disposal. Traditionally, when backfilling method was utilized in a
