The glacial drift with copper as a constituent was/is widespread across the central part of North America (Salisbury 1885 ), and occurred south and west of Lake Superior as far as Iowa and the Dakotas. In addition to such areas, the bedrock veins were also systematically visited and mined over many thousands of years.

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 ...

Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is ...

The SX/EW Process. The SX/EW Process is a hydrometallurgical process since it operates at ambient temperatures and the copper is in either an aqueous environment or an organic environment during its processing until it is reduced to the metal.

The main raw material is copper sulfide ore, and high-grade copper oxide ore can also be smelted in the pyrometallurgical process. The mining grade of copper sulfide is 0.3–2%, and the average mining grade is approximately 0.81%. The mined ore is crushed and pulverized. Then flotation will separate the copper sulfide concentrate.

The resulting copper matte consisting of Cu 2 S is then roasted to change all sulfides into oxides. 2 Cu 2 S + 3 O 2 ---> 2 Cu 2 O + 2 SO 2. The cuprous oxide is converted to blister copper upon heating: 2 Cu 2 O ---> 4 Cu + O 2. This step exploits the relatively easy reduction of copper oxides to copper metal.
