摘要
///In order to provide scientific evidence for in-depth evaluation of the quartzose sandstone of Huangdan, Muchuan County and high-end application in the quartz sand with lower iron, the iron reservoir state in the ore was studied with a variety of mineral test and analysis methods including X-ray fluorescence spectrometry analysis (XRF), X-ray powder diffraction analysis (XRD), scanning electron microscope (SEM) and X-ray energy dispersive analysis (EDS). The results show that the content of Fe2O3 in raw ore is about 0.161%, and the changing range is 0.086%~0.272%. The content of Fe2O3 in the ore is negative correlated with the content of SiO2 and particle size, and positive correlated with the content of SO3, Al2O3 and K2O. The content of quartz whose particle size is in the range of 0.2~0.5 mm is higher than 90% and there is no isomorph in the quartz crystal structure.
