Spirals also find application in the beneficiation of beach sand minerals, such as ilmenite, rutile, leucoxene, zircon, and monazite. In view of the steel industry requirement to reduce the silica, phosphorous, Al 2 O 3, and K 2 O levels in concentrates, spirals have been invariably used to enrich iron ores. Separation of chromite from silica ...
