Abstarct: The trace elements Se, Te, In, Ga, Ge are used in the manufacture of solar panels, they are a by-product of copper and lead-zinc deposits. Considering the end of fossil fuels, Iran's position in the world's solar belt, and the presence of Iran in the global belt of copper, In this research, mineral chalcopyrite chemistry is studied in some Iranian copper deposits for explore trace elements. Mineralogical studies on 55 polished sections and electron micro probe analysis on 57 points of chalcopyrite, x-ray microprobe analysis on 18 point of chalcopyrite and bulk analysis of ICP-MS on 5 samples )Sarcheshmeh, Sarkouh, charGonbad, PanjKohh and Qaleh Zari copper deposits) was done . baxsed on the results of ICP-MS analysis on bulk, selenium content was 39.5 to 118 ppm, tellurium content in Sarcheshmeh and Sarkouh 0.3 and 0.4 ppm, gallium to 1.51 ppm, germanium is 0.08 to 0.32 ppm and the indium is 0.03-0.28 ppm. In the results obtained from the electron micro probe analysis on chalcopyrite, the concentrations of the indium element are up to 700, germanium to 700, gallium to 500 PPM. In XPMA spot analysis studies, selenium levels were found to be only 142 ppm in the Qale-zary. Regarding the presence of sulfasalts containing selenium in the form of inclusion in Chalcopyrite Qaleh Zari, high levels of selenium in powder samples and XPMA analysis of Qale-Zari region are introduced for the detection of suitable trace elements.
