摘　　要：目的:考察来自安徽、河北、辽宁、四川和云南省的自然铜生品以及煅品的差别。方法:自然铜煅制醋淬后粉碎过筛,取生品和煅品的X射线衍射图谱进行比较。结果:结果表明,生品中的FeS2大部分在800℃时转化为Fe7S8。结论:自然铜生、煅品的X衍射分析方法专属性强,准确可行,可作为二者之间区分鉴别的手段。AIM： To investigate the difference between pyrite （pyritum） and processed pyrite from Anhui,He-bei,Liaoning,Sichuan and Yunnan provinces. METHODS： Pyrite was calcined with vinegar,ground and sieved. X-ray diffraction spectrum of both pyrite and calcined pyrite was compared to observe the change of composition in before and after the calcination. RESULTS： The spectrum showed that FeS2,occupied by pyrite,mostly converted into Fe7S8 at 800℃ after calcination. CONCLUSION： The method of X-ray diffraction analysis of the crude and processed product of pyrite has good specificity and is accurate and feasible and can be used to distinguish the crude and processed product of pyritum.
