### Mineral processing - Wikipedia

Mineral 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 important considerations are the economics of the processes and this is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation required and the processes that can occur. The smalle

### Mineral Processing - an overview ScienceDirect Topics

In any mineral processing operation, the term ‘benefits of scale’ is used to denote the significant economic advantages can be obtained by having larger production volumes and using larger ships. Larger tonnage operations operate with fewer man-hours per ton, while capital costs for larger machines are less than the multiples of their relative production capacities. In order to compete on ...
