Dry and Wet Screening in Mining: What are the Differences?

The screening decks are using vibrational energy to separate precious minerals. There are chunks of dirt and clay on the deck bottom. Some of these aperture-clogging chunks cannot pass through the screens, no matter how much oscillating motion is applied. Wet screening systems add water to the mix.

Screening

Screening is the separation of material into 2 - 6 different sized products. The material is separated by passing it through a vibrating 'screen box' which has a number of different sized screens, or meshes, which the material falls through like a seive.
