在世界含金矿物资源中,含金砷黄铁矿占有不可忽视的地位,1944年,Schwartz在综述中列出的115个矿区,便有45处明显表现出砷金共生关系,也许受当时检测手段限制,作者虽发现在其它矿区中也存在有砷黄铁矿,但未发现有明显结构关系.随着电子显微镜及电子探针的应用,人们才更清晰的确认细粒金(或固溶体形态)浸染于砷黄铁矿这一事实,据对美国柯特兹和卡林矿的矿石研究表明,金和砷共同集中于粒度≤0.05毫米黄铁旷微粒中或较大颗粒的棱角上. Among the world’s gold-bearing mineral resources, gold-bearing arsenic pyrites occupy an undeniable position. In 1944, out of the 115 mines listed by Schwartz in the survey, 45 showed a marked symbiotic relationship with arsenic gold, which may be affected by the current test Although the authors found that there are arsenopyrite in other mining areas, no obvious structural relationship was found.With the application of electron microscope and electron probe, it is more clear to confirm that the fine gold (or solid solution form ) Was disseminated to arsenopyrite, a study of ores from the Curtiz and Carlin mines in the United States showed that both gold and arsenium are concentrated in the χ0.05-mm yellow-iron particles or in the corners of larger particles.
