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 r
Mechanical screening, often just called screening, is the practice of taking granulated ore material and separating it into multiple grades by particle size.
This practice occurs in a variety of industries such as mining and mineral processing, agriculture,tical, food, plastics, and recycling.
