In order to develop a separation technology for metal recovery from scraps, we have studied density segregation in a particle bed by horizontally circular motion with a constant radius. Differences in the size and density of the particles and also in the velocity and radius of the circular motion affected the segregation of metal particles (Al or Pb) in a separation medium (ZrO2) were investigated. The optimum velocity and radius of circulation were 2.5 ~ 3.3 s-1 and 1.5 ~ 2.0 cm respectively. A new separation system was designed for the purpose of recovering Al or Pb particles from Al-Pb mixture using ZrO2 beads bed as a separation medium with horizontally circular motion. Al and Pb were continuously separated from mixture and the Newtons separation efficiency was 0.78. It was possible to recover both Al and Pb with high grade, and the grade of Al and Pb recovered was 99.9 % and 95.4 % at optimum condition.
