金矿的^(57)Fe穆斯堡尔谱研究

^(57)Fe MOSSBAUER SPECTRA STUDY OF GOLD MINE

金矿的成份用XRF谱、X射线谱、穆斯堡尔谱分析了各地十二个样品,测出除金以外有少量的FeS_2,FeSb_2S_4,γ-Fe_2O_3和Fe_3O_4.我们分析实验数据把金矿分成三部分,用不同的炼制方法除去铁.

Twelve samPles from different mineral lands Were analysed by elemental (XRF ) , Mossbauer sPectrascoPic and X-ray diffraction etc. , they determined main elemental composition and phase component of gold mine. Mossbauer parameters of Fe2+, Fe3+in gold mine including a few Pyrite( FeS2 ) , antimonite(FeSb2S4 ) , phrrhotite, γ-Fe2O3 and magnetite ( Fe3O4)were emphatically given. We analysed these experimental data and divided gold mine into three types, each type may be taken different refining ways of taking out iron.
