    2005-1-1  The Knelson concentrators are commonly used in the gold industry as gravity concentration devices because of their ability to recover coarse and fine gold from both alluvial and primary deposits. The device is most commonly installed ( Banisi et al., 1991 ) in the grinding circuit of a gold operation, where gold often accumulates due to its grinding and classification behaviour.
