While the dredge removes the material from the front end of the pond, the tailings generated by the separation process is stacked at the back; as a result the pond continuously moves in a forward direction.Burrowing into the mining face of the dune, the dredger advances at a rate of two to three metres per day, depending on the height of the dune. As the sand face is undermined it c...

  • Beneficiation - Wikipedia

    In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (concentrate) and a waste stream ().Examples of beneficiation processes include froth flotation and gravity separation.. Other economic uses of the term are in use.
