Abstract
Research was done on anodes for use with fluidized bed cathodes for electrowinning copper. Suitable anodes must have low power consumption (less than 3 kilowatt hours per kilogram of copper) while operating at high current densities (several thousand amperes per square meter). The anodes must also be free of operating problems and suitable for scale-up. The research resulted in a cell with energy consumption rates less than in conventional cells up to a current density about 10 times greater than in a conventional cell. The anode was tested on both a small, 50-ampere cell and on a larger, 1,000-ampere scale. Auxiliary experiments were carried out on the fluidized bed electrowinning of copper from dilute solutions, from dilute solutions containing cobalt and nickel, and from dilute chloride solutions.
