Producing Tungsten Concentrates. Cone crushers and ball mills reduce the size of the ore to under 2mm in size. Water carries the ore over shaker tables to concentrate it. It works like panning for gold in a river. The ore particles with lower density flow off as tailings while the higher density tungsten concentrate remains.
