Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
As in all mining operations, the ore must usually be beneficiated concentrated. The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals such as
The acid consumptions curves for the oxide copper ore number 3 with a high iron oxide tactile gangue were somewhat different than those of oxide copper porphery gangue ore number 1. In tests 9 through 14 the incremental acid curves were generally low at the start, fairly high after 3 to 4 days of leaching, and very high thereafter.
Oxide ores These ores contain metals in oxidized forms. Unlike sulfide ores, oxides need much more energy to achieve melting. For this reason, the hydrometallurgical approach is generally used to refine these ores.
Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores 1114, but is introduced here because an important by product of this process is used for the extraction of oxide ores.

the Middle Ages, the oxide ores had largely been exhausted. Learning from the Roman experience with seepage, the Moors developed open pit min ing, heap leaching, and iron precipitation tech niques that continued to be used at Rio Tinto into the 20th century. In Britain, copper and tin were worked in Corn wall and traded with the Phoenicians as early as 1500 B.C. The Remans brought improved
The principal copper ore mineral is chalcopyrite CuFeS2, whichmonly smelted to yield a matte containing ~50 copper. In the presence of silica flux, iron is selectively oxidized to a slag. Figure 14 shows a PSD for the CuFeSO system at 1 atm SO 2 as a function of temperature Rosenqvist, 1978.
The concentrate is then purified further through a refining process. The copper is now nearly 99.99 pure, and is cast into distinct shapes, ready for shipping to world markets. Step 4. Oxide ore treatment process: Copper is liberated from oxide ore through a chemical process known as leaching and solution extraction. The final step is
Extraction and refining. The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituentssuch as alumina, limestone, pyrite, and silicaso that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper.
Usingpact mining equipment, copper ore is extracted from the mine. After the ore is crushed, its roasted, which helps to convert sulfides to oxides. The oxides are smelted to produce matte, which then undergoes several refining processes.
Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile Escondida mine and Indonesia Grasberg mine. These produce many millions of tonnes of copper ore per year.
There are two main types of copper ore of interest: copper oxide ores and copper sulfide ores. Both ore types can be economically mined, though they are processed in different ways. Copper sulfide
