  • Mineral processingWikipedia

    Mineral processing can involve four general types of unit operation: comminutionparticle size reduction; sizingseparation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewateringsolid/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.
