Abstract: The present invention provides a sorting method and a sorting device for sorting particles according to their settling velocities in a fluid medium. According to one aspect, the sorting method comprises admitting particles into a longitudinally vertically positioned container containing a fluid and allowing the particles to settle for a specified period of time under the influence of gravitational forces resulting in separation of the particles according to their settling velocities, followed by rotating the container by 90 degrees in order for the container to take a longitudinally horizontal position and thus allowing the separated particles to settle down and be collected in a sorted fashion. The sorting device comprises a container and means for achieving sorting of particles using this sorting method.
