Mineral processing

Overview

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 considere
