Enhanced Metal Recovery in Fluidized Bed Electrodes with a Fin‐Type Current Feeder

Abstract

A rectangular side‐by‐side fluidized bed electrode for metal recovery from dilute copper solutions was investigated. Because the contacts between fluidized particles and current feeders are particularly important, fin‐type current feeders were used to enhance the deposition rate. Polarization curves with a fin‐type current feeder were measured at various Reynolds numbers. It is shown in the experiments that fin‐type current feeders provide higher deposition rates for the same electrode potential than planar current feeders in fluidized bed electrodes.
