El dispositivo es un aparato de concentración por gravedad, que recupera piezas de oro fino del mineral sin tener que utilizar cianuración de oro, un proceso costoso que utiliza productos químicos para extraer oro del mineral.

Knelson™ and Falcon Concentrators Popularized Gravity Centrifuges. The development of fluidized gold centrifuges has a rich history, starting in Australia in the 1930's. However, the equipment was not popularized until the development of the Knelson™ and Falcon concentrators in the 1980's.. The Knelson™ concentrator consists of an inclined, constant-angle bowl wall …

These apparatus, Knelson and Falcon Superbowl gravity concentrators, provide good recoveries for very fine particles up to 38μm and finer. These gravity separators and their uses have been described in many papers. 2,3,4,5. The fundamental approach of the behaviour of mineral particles in these apparatus has not been studied until now.

The overall bowl angle of the Knelson™concentrator is approximately 13 degrees from vertical. Because this angle is shallower than the dynamic slurry face, the slurry can freely exit and there is no slurry face created in the bowl. Like the riffles in a sluice box, the Knelson™riffles create small eddy currents as the slurry falls over each riffle.
