Continuous Gravity Concentration in Gold Gravity Circuits

Falcon in the grinding circuit. By recovering 15% of the feed mass on a small Falcon C1000 (30t/h) and treating only 12% of the cyclone underflow, one can easily recover over 80% of the gold by using continuous Falcon gravity units in the grinding circuit. Typically a batch type concentrator would be treating greater than 20% of the cyclone
