Uralelektromed has completed installation of electrolytic cells in the tankhouse under construction

Verkhnyaya Pyshma (Sverdlovskaya oblast)

JSC “Uralelektromed” (UMMC Group) has completed erection of CTI polymer-concrete cells at the 2nd stage of copper tankhouse being under construction since 2014. Total number of cells is 448. They were lifted with KUENZ crane using two 5t hoists.

Copper will be refined in these electrolytic cells according to permanent cathode technology (permanent stainless steel cathodes are used instead of starting sheets). According to Aleksey Korolev, chief engineer, these electrolytic cells admit 63 anodes and 62 cathodes that is almost twice as much if compared with conventional technology (using starting sheets). “In this way we can produce Grade A cathodes with copper content 99.99 %”, he said.

The cell is made of electrolyte-resistant material- polymer and high-silica sand and has a service life over 20 years. Each cell weights 7.5 t. Further sealing between cells and piping will be performed.

Nowadays, integral electric and auxiliary rooms are being constructed, light railways are laid and forced ventilation system with heat recovery is installed. All heating systems and process equipment are planned to be erected in 2017.

It is appropriate to recall that due to launching of the 2nd stage of tankhouse, copper cathode production capacity will increase to 320,000 tpy. 2.7 bln rubles will be invested in the project. Total investments equal 4.6 bln rubles. The first stage of the tankhouse was put into operation in 2012. Over 4.4 bln rubles were invested therein. Currently, the tankhouse has reached its designed capacity 150,000 tons of copper cathodes and even exceeded it.
