Copper extraction - Wikipedia

Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper-in-concentrate (usually 27–29% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite, sphalerite or galena. Chalcocite concentrates typically grade between 37% and 40% copper-in-concentrate, as chalcocite has no iron within the mineral.

THE RECOVERY OF COPPER, IRON, AND SULFUR FROM CHALCOPYRITE ...

chalcopyrite concentrate liberates sulfur on heating to form a high-temperature phase of chalcopyrite which may be in coexistence with either iron sulfide or copper sulfide depending on the copper/iron ratio in the original concentrate. The efficiency of reduction is then based on the sulfide component that is most difficult to reduce.

Copper Mining and Extraction: Sulfide Ores

The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. For example: FeO(s) + SiO 2 (s)→ FeO.SiO 2 (slag) This is very similar to the removal of impurities in the blast furnace.

In a recent pilot plant trial, copper extraction of a selected concentrate above 95% with elemental sulfur yields of 60% were achieved after 2 h at 150 °C (Dreisinger et al., 2003). The addition of surfactants was found not to affect extraction or phase separation in the subsequent SX process as these materials are decomposed during pressure oxidation.
