ABSTRACT:
A spiral trough separator for treating a slurry of ore particles in water to separate heavier fines from other particles includes a helical trough making a plurality of revolutions around a vertical axis and having the surface of the trough modified with protuberances to agitate the ore particles to allow entrapped impurities to be liberated and grooves to provide enhanced flow of the finer heavier ore fines closer to such axis to increase the efficiency of the recovery.
