Beneficiation - Wikipedia
Beneficiation can begin with in the mine itself. Most mines will have a crusher within the mine itself where separation of ore and gangue minerals occurs and as a side effect becomes easier to transport. After the crusher the ore with go through a grinder or a mill to get the ore into fine particles.Read more
