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-

Description. Iron Ore (fines) Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite …

The bed of the iron ore fines formed on the dewatering screen can be thought of as a cake of fine and ultrafine mineral particles on a filter cloth.
