The copper blister from the conversion process in the smelting unit in Sarcheshmeh Copper Complex undergoes thermal treatments and the impurities are removed from that, leaving us with anodic copper.

The Anode Furnace #4, as part of the project of Sarcheshmeh Copper Complex expansion, was procured, installed, and operationalized by NIPEC and the technology providing company, Outotec.
