the ore delivered to the screening plant would be highly sticky. When fines are firmly adhering to lumpy ore, it would be advantageous to scrub the ore in a blade or other type of washer to loosen the fines before wet screening. When wet screening is preceded by scrubbing, the entire opera-tion is called 'washing'. Fines obtained as screen under-
For high grade ore, crushing and dry screening are sufficient to give desired quality material. Some times wet screening is done by introducing high pressure water, jets over screens, fines are classified and ultra fines are deslimed by hydrocyclone.
