WebFor removal of the gangue minerals, including iron-bearing minerals, beneficiation is mandatory prior to the smelting process [4,5,6]. Conventionally, the chromite ore is beneficiated by using gravity concentration techniques. ... Beyond a specific limit, it is challenging to process these iron-bearing minerals by using conventional gravity ... Disaggregation 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.
