Screening in Mineral Processing and The Importance of

Screening plays a significant role in a lot of industries. It separates the valuable minerals and materials from the waste rock, debris, and other excessive elements that are not needed for further processing. This process mostly occurs in a huge variety of industries like mining, mineral processing, agriculture, pharmaceutical, food, plastics, and recycling.

What are the Four Types of Mineral Processing?

Further research led Andrew to the Wikipedia page for mineral processing which states, “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.”
