The mineralogy and bulk chemical compositions of three iron meteorites (Zhaoping, Xifu and Hami) recently found in China are reported here and the three irons are made classification on the base of their bulk chemical compositions. Zhaoping contains 93.4 mg/g Ni, 85.9µg/g Ga, 418µg/g Ge, 5.24mg/g Co,1.94µg/g Ir, 0.774µg/g W, and 1.62µg/g Au. Zhaoping belongs to the low-Ni, low-Au subgroup of IAB.It is a coarse octahedrite and consists of kamacite, taenite, troilite, schreibersite and cohenite. Cohenite has entirely decomposed to graphite and low-Ni kamacite in our samples. Zhaoping contains some inclusions of Mn-free sarcopside which were rarely reported in IAB iron meteorites. Xifu has 74.1mg/g Ni, 58.8µg/g Ga, 150µg/gGe, and 0.913µg/g W. Xifu is a member of group IIICD iron meteorite. Like most of IIICD irons,Xifu is a coarsest octahedrite with kamacite bandwidth of > 3 mm, and contains kamacite, taenite and schreibersite. Carbides and graphite are not found in the sample due to the sample heterogeneous. Hami has 106mg/g Ni, 5.36mg/g Co and 0.922µg/g Ir. Ga and Ge contents in Hami were not obtained because of the low concentrations and the limited precision of INAA technique. Hami is an un-grouped iron meteorite on the basis of the contents of other trace elements, structure and mineralogy. In mineralogy and structure, Hami resembles to Rafruti, another un-grouped iron meteorite.
