Abstract:As a newly developed insoluble anode, titanium based lead dioxide anode plate has been gradually applied in the purification process of copper electrolyte. Earlier, due to the limitation of material and process, the coating of PbO2 is prone to fall off,which affects the service life of this kind of anode plate. In recent years, manufacturing technology has made great progress and problems have been solved. Even some new copper electrolysis workshops have been directly applied on a large scale. In this paper, the traditional lead alloy anode plate and titanium based lead dioxide anode plate are compared and analyzed in terms of current efficiency, power consumption, product quality, service cycle and production operation under the same working conditions. Compared with the traditional lead alloy anode plate, the current efficiency of titanium based lead dioxide anode plate is increased by 7.85%, product quality is better, the service cycle is more than twice, the flatness of plate surface is relatively stable and production and operation efficiency is high, but the power consumption of copper removal is 10% higher, and short circuit will melt through the plate surface in copper removal production. The above provides a reference for the economy of selecting insoluble anode in copper electrolyte purification process.
