Waste Rock and Ore Tailings Crushing Machine

Waste Rock is the rock which was given up because it was supposed to be useless. Waste Rock from coal mine is called coal gangue. Iron Ore mine, gold mine, coal mine and limestone mine usually give up lots of waste rock.

Ore tailings were given up by the ore dressing plant. Usually they have already been grinded into fine particle size but were unable to be used. According to the national regulation, ore tailings shall be stored in the ore tailing pond. If the height of tailing dam is too high and beyond the designed standard or safety requirement, there will be potential safety hazard.

Hence, how to dealing with those waste rock and ore tailing are concerned by more and more people.

In China, after crushed by crushing machine, such as jaw crusher, impact crusher, cone crusher, and then screened by the vibrating screen, those waste rock are used as concrete aggregate or Inorganic mixture in the road building industry. Waste rock from iron ore mine is the ideal material of railway ballast because of its low hardness and small specific gravity.
