By Mahmut MAT - Modified date: 05/09/2023 Chalcopyrite is a mineral and ore of copper. Its chemical composition is CuFeS2, meaning it contains copper (Cu), iron (Fe), and sulfur (S). Chalcopyrite is one of the most important copper ores and is widely distributed in various geological environments.Abstract The transition to renewable energy infrastructure necessitates rapid growth in copper production, averaging at least 3.5% annually to 2050. The current smelting–converting–electrorefining route must be revisited considering these future prospects as ore grades deplete and the costs to mitigate emissions to the environment increase.Electrolytic production of copper from chalcopyrite - ScienceDirectChalcopyrite is an important ore of copper found in a wide range of hydrothermal environments.
