A separator pan (10) is set into a rearwardly leaning position (Fig. 4). A lower portion of the pan sidewall (28) slopes downwardly as it extends outwardly from the pan bottom (12). A spiral rib (32), inside of the pan (10) slopes upwardly as it extends axially outwardly from the interior of the pan (10). Pan (10) is rotated in a direction causing the spiral rib (32) to coil inwardly. Large particles of gold ore, introduced into the pan (10), gravitate out from the pan, owing to the sloping nature of the lower portion of pan sidewall (28). Smaller particles, including small particles of gold, are trapped between spiral rib (32) and sidewall (28) and bottom wall (12) of pan (10). As the pan (10) rotates, these small particles are moved inwardly and into a hub cup (14).

Récipient conique de lavage de matériaux (10) utilisé en position inclinée vers l'arrière (voir figure 4), de manière que la paroi (28) décrive à la partie inférieure un angle descendant par rapport à l'horizontale. Une nervure en spirale (32) sur la paroi intérieure monte du fond vers le bord du récipient (10). Le récipient (10) est tourné de manière à imprimer à la nervure (32) un mouvement de spirale descendante. Les grosses particules de minerai d'or se déposant dans le récipient en ressortent par gravité du fait que la paroi (28) du récipient (10) est dirigée vers le bas. Les petites particules de minerai ou d'or demeurent captives entre les spires de la nervure (32) et le fond (12) ou la paroi (28) du récipient. La rotation du récipient (10) fait descendre ces particules le long de la nervure (32) jusque dans un rétrécissement (14) au fond du récipient (10), où elles sont collectées.
