Extraction Of Copper | Mining, Concentration, Smelting

The reaction of these processes can be written as: 2CuFeS2+2SiO2+4O2 → Cu2S+2FeSiO3+3SO2. The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. Cu2 S+O2 → 2Cu+SO2.

The Extraction of Copper

The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.

12.3 Primary Copper Smelting

Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4 Mining produces ores with less than 1 percent copper.

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.

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.

Copper Processing | Multotec

Copper processing begins with mining copper ore, which contains less than 1% of copper, and ends with sheets of 99.99% pure copper (cathodes). Copper mining generally takes place through open-pit mining, in which a series of stepped benches are dug deeper into the earth. Yet, it can also be mined underground, through horizontal …

Copper Statistics and Information | U.S. Geological Survey

Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode. An increasing share of copper is produced from acid leaching of oxidized ores.
