What is Copper oxide?
Copper oxide (CuO) is a semiconducting compound with a monoclinic structure. CuO has attracted particular attention because it is the simplest member of the family of copper compounds. It exhibits various potentially useful physical properties, such as high-temperature superconductivity, electron correlation effects, and spin dynamics. Copper oxide is relatively cheap, easily mixed with polarized liquids (i.e., water) and polymers, and relatively stable in terms of both chemical and physical properties. Highly ionic nanoparticulate metal oxides, such as CuO, may be valuable antimicrobial agents as they can be prepared with extremely high surface areas and unusual crystal morphologies. Copper oxide (CuO) nanoparticles have been characterized physically and chemically and investigated concerning potential antimicrobial applications. It was found that nanoscaled CuO, as generated by thermal plasma technology, demonstrated particle sizes in the range of 20–95 nm with a mean surface area of 15.7 m2/g. CuO nanoparticles in suspension showed activity against various bacterial pathogens, including MRSA and E. coli, with MBCs ranging from 0.1 to 5.0 mg/mL.
Flotation of Oxide Copper
The flotation practice of oxide copper minerals dates back almost 60 years ago and has been applied in Central Africa (Congo) by Union Miniere (Belgium). The process involves two basic flotation methods: (a) fatty acid flotation of oxide copper minerals from siliceous ore and (b) subsidization of oxide copper minerals followed by flotation using sulfhydryl collectors, such as xanthate [1] from carbonate ores. In the past 50 years, extensive research has been carried out on various oxide copper minerals, and only a few of the many innovative processes have been introduced into operating plants. It was not until recently that new technology was developed and introduced into some operating plants worldwide. One of the major problems with the flotation of oxide copper minerals at the industrial scale is that the floatability of oxide copper minerals from natural ores depends largely on the mineralogy of the ore and the gangue composition. The floatability of oxide copper minerals in the ore containing carbonaceous and dolomitic gangue significantly differs from the flotation properties of oxide copper containing siliceous gangue minerals.
Peculiarity of copper oxides
Copper oxides are unusual in two respects. First, octahedral-site CuII:t6e3 contains a single e hole in the 3d shell, which makes it orbitally degenerate and, therefore, a strong Jahn–Teller ion; consequently, CuII ions normally occupy square coplanar, pyramidal, or octahedral sites that are deformed to tetragonal (c/a > 1) symmetry by Jahn–Teller orbital ordering. However, without cooperativity stabilizing long-range orbital ordering, the electrons may couple locally to E-mode vibrations, forming vibronic states in a dynamic Jahn–Teller coupling. Second, the CuII:3d9 energy level lies below the top of the O2 −:2p6 valence band in an ionic model; the introduction of covalent bonding creates states of e-orbital symmetry at the top of the O2 −:2p6 bands that have a large O-2pσ component.
