XRD Determination of the Main Phases and the Main Elements of Minerals

X-ray diffraction method was used for analysis of the main phases of copper concentrate, lead concentrate, zinc concentrate and oxide skin and TOPAS software was used to determine the content of the main elements. The main phases of copper concentrate were chalcopyrite, pyrite and quartz. The main phases of lead concentrate were galena, lead alum and white lead. The main phase of zinc concentrate was sphalerite. The main phases of oxide skin were ferrous oxide, iron oxide and ferric oxide. XRD patterns were fitted by TOPAS software for determination of the content of copper in copper concentrate, the content of lead in lead concentrate, the content of zinc in zinc concentrate and the content of iron in oxide skin. The results were consistent with those obtained by the standard method.
