Characteristics of the copper recovery from the wastewater of an industrial field were studied in two and three-phase fluidized-bed reactors. The operating variables used in this study were the liquid velocity (UL), current density (I), distance (LAC) between the two electrodes, and the amount of fluidized solid particles (W). The two-and three-phase fluidized-bed reactors were made of an acryl column (deameter: 0.102 m; height: 1.0m). It was found that the recovery ratio of the copper powder showed a maximu value with an increase of the liquid velocity, and with an increase of the distance between the two electrodes or the amount of fluidized solid particles added to the reactor; it increased gradually upon increasing the current density between the two electrodes in both the two- and three-phase fluidized-bed reactor systems. Also, it was verified that the efficiency of the copper recovery in the three-phase fluidized-bed reactor was more effective than that in the two phase fluidized-bed reactor under a relatively low gas velocity.
