The fundamental principles of spiral gravity separation are analyzed in this paper. Fig.1 illustrates the essence of the situation. A sphere placed on a downward slope gains a rolling forward velocity. The downward slope is also inclined towards the central axis so that an inward force, F INWARD, acts on the rolling particle.
