STUDY ON OCCURENCE FORM OF PLATINUM IN XINJIE Cu-Pt DEPOSIT BY NAA AND SCANNING PROTON MICROPROBE 1 first-author 1 1 1 2 2 2 2 Shanghai Institute of Nuclear Research, the Chinese Academy of Sciences, Shanghai 201800 Shanghai Institute of Nuclear Research, the Chinese Academy of Sciences, Shanghai 201800 Institute of Applied Nuclear Techniques, Chengdu Institute of Technology, Chengdu 610059 Institute of Applied Nuclear Techniques, Chengdu Institute of Technology, Chengdu 610059 A combination of NAA and micro-PIXE was used to study concentrations and distributions of platinum group elements (PGE) in ores from Xinjie Cu-Pt deposit. The NAA results of the bulk indicate that the ores belong to the enriched Pt-Pd type. The element concentration maps of scanning micro-PIXE for the ores show that the occurence form of Pt is independent arsenide minerals. No PGE were detected in chalcopyrite of Xinjie Cu-Pt deposit. These information are economically beneficial to the mineral smelting process.
