Copper Life Cycle
After mining, copper is produced by one of two process routes, pyrometallurgical (dry) or hydrometallurgical (wet). Smelting is a process of heating and melting ore to extract a metal like copper. Refining refers to any process that increases the grade or purity of the metal. After completing refining processes, copper cathode is generally 99.9 ...
