Beneficiation - Wikipedia

Beneficiation can begin within 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 will go through a grinder or a mill to get the ore into fine particles. Dense media separation (DMS) is used to further separate the desired ore from rocks and gangue minerals. This will stratify the crushed aggregate by density making separation easier. Where the DMS occurs in the proc
