Processing sulfur technological gases formed in pyro-smelting copper concentrate processing in a smelting furnace and the converters in metallurgical production results in sulfuric acid production. Two systems for sulfuric acid production are used and managed with an automatic system. Sulfuric acid is intended both for external clients and internal needs. The wastewater purification plant receives the wastewater from all production facilities. It is cleaned to remove heavy metals and neutralized before it is safely disposed of in natural water sources.
