spiral concentrators will tolerate minor feed variations without requiring adjustment. spiral concentrators like cone concentrators are efficient low-maintenance units that should be considered for any large- scale gravity separation system. the newer humphreys spirals are capable of recovering particles as small as 270 mesh (53 microns).
for good separation the density difference between the heavy minerals and the light minerals in the feedstock should be at least 1 g/cm 3; and because the separation is dependent upon size and density spiral separators are most effective at purifying ore if its particles are of uniform size and shape. a spiral separator may process a couple
