One of the links in the tellurium production scheme at the Pyshminsky Copper Electrolyte Plant is the electrolytic separation of tellurium concentrate from solutions from aqueous leaching of soda-tellurium slag. Stainless steel grade 1X18N9T is used as anodes, which has proven itself in alkaline environments. However, during the industrial operation of the electrolytic plant, corrosion of the anodes was revealed, which led to a violation of the electrolysis regime.
