Ore sorting is a completely dry process which requires no water. In fact, it's necessary for the input material to be completely dry. This is great when resources are scarce, or conserving water is critical. However, this can also work against operations in parts of the world with heavy amounts of precipitation or groundwater.
Get MoreMineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most ...

Get MoreTo date, most members of the mining and mineral processing industry have been aware of ore sorting and the benefits it offers. Introduced nearly thirty years ago, sorting was first adopted by the diamond and precious metal industries. In these sectors, the value of the minerals sorted was so high that the capital payback could be easily justified.
Get Moresizing and sorting process help removing larger particles and other unnecessary impurities in the ore material. Through those process, ore particles with good particle size are obtained, and the efficiency and benefit of beneficiation are improved.
