Chelyabinsk zinc plant switches to rolled anodes

At the Chelyabinsk zinc plant began the transition to rolled anodes. Since the launch of the electrolysis of zinc on the Chelyabinsk branch of used anodes are cast from alloy of lead and silver. Experience at high current loads showed that they have low mechanical properties and high corrosion rate. As a result, the number of Transconductance circuits, reduced the release of zinc current and increases the specific consumption of electricity for electrolysis.
after reviewing the latest scientific data and experience of the modern zinc plants, the initiative group of specialists of the plant "Complex electrowinning of zinc" suggested the use of anodes produced by the method of hire. Were carried out industrial tests of rolled anodes, which showed their resistance at high current loads.
"the Test showed that when working on the rolled anodes increases the performance of electrolysis and reduced specific energy consumption for each released ton of zinc, - said the head of the shop Complex electrowinning of zinc Denis Camerase. – In addition, the service life of the anode is increased by almost half. The expected economic effect of the transition to the use of rolled anodes will be more than 400 million rubles a year."
All anodes are cast anodes (16 524 pieces) will be replaced by rolled before the end of 2023.
