Elemental analysis of a representative quartz sample showed that the quartz deposits were classified as medium purity quartz with 99.575% average SiO2 content and about 0.422% (4220 ppm) of accompanied mineral. Field study and petrography investigation using optical polarized transmitted microscope and reflected light microscope revealed that these impurities were mainly found as solid particulates of iron oxide, muscovite, rutile, orthoclase, granitic rafts, and as fluid inclusions as well. Moreover, structural undesirable trace elements were also presented in the quartz sample.展开更多
