Abstract

In recent years, there has been a growing focus on the reuse of met­al­lic components from waste electrical and electronic equipment (WEEE) which refers to electrical and electronic equipment that has become obsolete, stopped working, or developed defects during production. In this research, shaking table was selected as a gravity concentration tool for the recovery of copper from the light components. The flowsheet included comminution, gravimetric concentration and physical/chemical characterization of feed material and pro­ducts. The process parameters were deck angle (degrees), motion frequency (Hz), wash water rate (L/m) and particle size diameter. The Box Behnken Des­ign (BBD) was used to optimize the performance of the wet shaking table and to identify the ideal combination of its operating parameters. By analysing the experimental design, it was found that the optimal settings for deck angle, mot­ion frequency, wash water rate and particle size diameter were 2°, 50 Hz, 12 L/m, and –500+300 mm, respectively. These optimal settings were located near the central points of the experimental design, suggesting that the actual optimal point could be within the designed space.
