How Copper is Extracted and Processed From Ore to Metal. The extraction of copper typically starts with mining copper ores, such as chalcopyrite, the most common copper ore. These ores are then refined to extract copper. The process involves crushing the ore, grinding it, and using flotation to separate copper from other materials in the ore.

Oxide Copper Ores . After crushing oxide-type copper ores, such as azurite (2CuCO 3 · Cu(OH)3), brochantite (CuSO 4), chrysocolla (CuSiO 3 · 2H 2 O) and cuprite (Cu2O), dilute sulfuric acid is applied to the surface of the material on leaching pads or in leaching tanks. As the acid trickles through the ore, it combines with the copper ...

Classification of copper ore Due to the different types of ore, the nature of the ore is also different, so the beneficiation process needs to be customized. The specific process for selecting copper ore depends mainly on the material composition, structure and copper occurrence state of the original copper ore.
