A tube density separator and method for use in a cotton gin to separate cotton from a pneumatically conveyed mixture of cotton and foreign materials has a generally vertical tube for receiving the mixture and separating out the foreign material from the cotton. The bottom of the tube is larger than the outlet of the pipe transporting the mixture so the velocity of the flow will be reduced and turbulence created. This action causes the heavier foreign matter to separate from and drop out of the cotton/foreign matter mixture. One or more dispersal rods are placed inside the tube to interact with the flow of material up the tube. The dispersal rods further break apart the clumps and wads of cotton and foreign matter to facilitate the separation action. The separated out foreign matter is collected at the inlet area of the tube. A supply of air, which can be skimmed from the air flow up the tube, conveys away the foreign matter from the tube.
