Spiral centrifuges concentrate and separate the heavy mineral sands from the lighter clays and quartz sand. The 80-percent heavy mineral concentrate is pumped to a stockpile area before being transported to a plant for further processing. The tailings of clays and quartz sand is discharged back into the pond behind the suction dredge.
