Heavy minerals / metals displace the lighter aggregate & clay materials and drop to the bottom of the spirals, aggregate & clay materials gravity flow towards the back, heavy minerals / metals are caught in the counter flow spirals and carried towards the front. Inner drum oversize material discharges straight off the back; Outer drum tailings discharge off the back to a side discharge chute; the recovered heavy minerals / metals captured in the outer drum counter flow spirals discharge off the upper feed end to a side chute.
