In the context of chemical processing, screening is the process of segregating materials and classifying them into different sizes or grades. There are two types of screening: dry screening and wet screening. Dry screening entails screening materials in their naturally mined state by way of vibration. The processor filters the material through physical screens, wherein particles of a certain size will pass through openings of a certain size. The smaller the particle size needed, the smaller the openings will be, which can make the screening process more difficult. This process can involve many screens for multiple distribution piles.
