Tenorite (CuO) nanoparticles were prepared from a dilute CuSO4 solution. The
solution was obtained by leaching (pH=1.5) of smelting furnace dust of
Sarcheshmeh Copper Complex, Iran. The recovery of copper from the acidic
sulphate solution was carried out by solvent extraction using Lix 984-N.
Tenorite nanoparticles were synthesized by direct thermal decomposition of
Langite [Cu4(OH)6SO4(H2O)2] as a precursor which was calcinated in air for 2
h at 750°C. The Samples were characterized by X-ray diffraction, infrared
spectroscopy, scanning electron microscopy, and transmission electron
microscopy. The average diameter of the spherical pure CuO nanoparticles and
their crystallite size were estimated to be 92 nm and 40nm, respectively.
The simplicity of the present method suggests its potential application at
industrial scale as a cheap and convenient way to produce pure CuO
nanoparticles from dilute CuSO4 solutions obtained from leaching of smelting
furnace dust.
