First, iron ore sorting through job processing, its main components have been enriched in the concentrate, after some after a comprehensive treatment, ore or other minor components of metal have to be recycled. Therefore, the remaining part of the product containing the ingredient with very low, which is part of the product known as tailings. The machine used to recycle tailings contain a lot of useful magnet material.
Second, the main technical parameters:
