Advances in Centrifugal Gravity Concentration

Most of the recent advances and increased use of gravity concentration has come with the development of centrifugal concentrators. Two units developed in Canada, the Falcon and the Knelson, have become popular for use within many grinding circuits where the presence of a reasonable amount of gravity recoverable gold has been identified in the ore. The units operate on a semi-continuous
