CuS thin film composed of nano/micro tubes with diameters in the range of 150 to 200 nm and lengths up to several microns and CuO thin film composed of nano/micro crystals with sizes ranging from 150 to 250 nm have been successfully prepared through a gas-solid sulfurization and oxidation reaction using well-aligned CuCl nanorod films as precursor.

Copper monosulfide (CuS) nanoparticles were synthesized by sonochemistry from an copper nitrate [Cu(NO3)2] and thioacetamide(TAA).

By the solvent thermal synthesis process,the nano-powders CuS were prepared applied CuCl2·H2O and CH4N2 as reactors,compound of ethanol and distilled water as solvent.

Synthesis of copper sulfide nano-particles by non-aqueous solvent method;

Study of flotation process with low alkalinity on a copper sulfide deposit;

According to the analysis results of ore mineral phase,the mixing flotation process of flotating copper sulfide and copper oxide and new high efficiency flotation reagent were adopted.

To treat a certain hydrothermal alteration contact metamorphic proterozoic copper sulphide mine,the mineral processing flowsheet and reagent system were investigated and adjusted,and a flowsheet,which is structurally simple and easy to industrialize,was proposed.

In our experiments of copper monomineral analysis, it has been discovered that when copper sulfide mineral is leached only with bromine solvent,a part of the copper sulfide mineral react to form precipitated black copper (CuO) resulting in an incomplete leaching of copper sulfide.
