Spiral separator - Wikipedia

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 ...
