Abstract
A separation arrangement is provided for separating between particles of different materials having different densities and comprised in a mixture of fine particles. The arrangement comprises: a solid particles feed ingress means, a solid particles pushing/pulling means and at least one mesh adapted to stop particles of the lighter material. The particles comprised in the mixture are allowed to free fall within the separation arrangement, and particles of the lighter material are being extracted away from the free falling particles by the solid particles pushing/pulling means and conveyed towards the at least one mesh. The particles of the heavier material are allowed to complete their free fall and to reach the lower part of the separation arrangement.
