Purpose of screening in mineral processing

Apr 08, 2020 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
