Knelson concentrator - Wikipedia
A Knelson concentrator is a type of gravity concentration apparatus, predominantly used in the gold mining industry. It is used for the recovery of fine particles of free gold, meaning gold that does of a centrifuge to enhance the gravitational force experienced by feed particles to effect separation based on particle density.
