Abstract:

Added value tax in import and customs duty are free for gold ore.One block of “gold ore” was checked by one Custom to identify its property.This paper demonstrates the product belongs to gold ore by X ray fluorescence and diffraction analysis and comprehensive analysis of appearance,physicochemical characteristics in its different state,which has natural characteristics and with gold content of 51.3 g/t,silver 815.5 g/t.The phases is dominated by quartz,sphalerite,galena,chalcopyrite etc.One identification program and method for gold ore is formed in order to offer scientific basis to Custom’s inspection.

Key words: gold ores, identification method, X-ray fluorescence spectrometer, X-ray diffraction, customs inspecti- on and supervision
