Copper is obtained raw (94-97% copper) by concentration, roasting and melting in electric or reverberatory furnaces. This copper is purified to 99% by melting in a reverberatory furnace with additives that form slag with the iron and nickel, and the existing copper oxide is reduced with carbon.
Subsequently, electrolytic refining is carried out, which is a mechanism for making the metal stronger against oxidation and making it look more attractive for decorative purposes.
The technical-chemical specifications of the electrolytic copper metal allow us to compete in international markets, especially in Europe and America.
