purpose of screening in mineral processing

Screening in Mineral Processing and The

Both the mining and mineral processing industry hugely utilise the screening process since it can effectively separate and filter out important minerals from the newly extracted materials. Once the minerals are filtered and separated from excess materials, they will be processed further depending on their commercial use.

Screening in Mineral Processing and The

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.
