rare because these ores are mostly subjected to hydrometallurgical copper recovery, for example, heap leaching. In Zambia and Zaire, however, siliceous copper oxide ores are floated with fatty acid collectors, and dolomitic copper oxide ores are sulfidized with sodium hydrogensulfide and then floated [48].

copper processing - copper processing - Ores: Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves.

Abstract: A method for producing copper oxide. In the method, a copper bearing material, aqueous ammonia, and a sufficient amount of an ammonium salt to double the rate of production of copper oxide in the absence of the salt are placed in a single vessel. The vessel is closed, and oxygen is fed into the vessel.

The copper-oxide superconductors all contain CuO 2 sheets in which any apical Cu-O bonds perpendicular to a sheet are significantly longer than the in-plane Cu-O bonds. This structural feature signals full occupancy of the (3z 2 –r 2) orbitals of an e-orbital pair.The parent compounds of the superconductive systems contain all Cu II in the CuO 2 sheets, which leaves the in-plane (x 2 – y 2 ...

In most cases, the thin-layer process was used where crushed ores (80% −0.5 in) were stacked in heaps of 3–8 m height after agglomeration and sprayed at flow rates of 6–40 L·hour −1 ·m −2 with 15–90 days duration for copper oxides and 10–18 months for sulfides. Of note, 80%–85% copper extraction was commonly achieved.

Copper and copper alloys are generally classified into four categories: copper (pure copper), brass, bronze and white copper. Copper brazing properties mainly depend on the stability of the surface oxide film and the influence of the brazing heating process on the material properties. Copper oxide and cuprous oxide can be formed on the surface of pure copper.
