Fine Gold Recovery
The i150 Gravity Concentrator is the smallest of the World famous iCONs. This is a gravimetric concentrator that uses enhanced gravity (G's) to concentrate the 'free' heavy minerals. It is also known as a centrifugal concentrator because of the centrifugal action of the spinning bowl. The process uses only water and an electric motor to concentrate …
