Dry and Wet Screening in Mining What are the Differences

Wet Screening Advantages 160 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.

Wills' Mineral Processing Technology ScienceDirect

In mineral processing, this is usually water, and wet classification is generally applied to mineral particles that are considered too fine to be sorted efficiently by screening. Since the velocity of particles in a fluid medium is dependent not only on the size but also on the specific gravity and shape of the particles, the principles of classification are important in mineral separations

The mining and mineral processing industry uses screening for a variety of processing applications. For example, after mining the minerals, the material is transported to a primary crusher. Before crushing large boulder are scalped on a shaker with 0.25 in (6.4 mm) thick shielding screening. Further down stream after crushing the material can pass through screens with openings or slots that continue to become smaller. Finally, screening is used to make a final separation to produce saleable products based on a
